AERODYNAMICS:

Advanced Topics in Aerodynamics (on-line manual). This web site is an electronic media about aerodynamics, aeronautics and propulsion systems. The topics presented are of general interest, more or less advanced. The site is addressed to the expert and non expert who have a prior knowledge of aerodynamics and fluid dynamics. There is no mathematics. Large use is made of graphics, figures, tables, summaries, reference to further reading. SUMMARY: Fixed Wing Aircraft, Helicopter and V/STOL Aircraft, Lighter-than-Air, Aerodynamic Decelerators, Wind Energy Systems, Racing Cars Aerodynamics, Wind Tunnel Testing, Buildings Aerodynamics.
Aerodynamics for Students. This web textbook contains information, data tables and computer programs for the study of Aerodynamics. Topics relevant to the undergraduate degree in Aeronautical Engineering are covered.
Airfoil Coordinates Database (UIUC).
Applied Aerodynamics: A Digital Textbook. This text was developed for a course in applied aerodynamics at Stanford University. The first year graduate course includes topics ranging from a review of the basic, governing equations of fluid flow to practical issues related to airfoil and wing design.
Beginner's Guide to Aerodynamics (NASA) . At this Web site you can study aerodynamics at your own pace and to your own level of interest. Some of the topics included are: Newton's basic equations of motion; the motion of a free falling object, that neglects the effects of aerodynamics; the terminal velocity of a falling object subject to both weight and air resistance; the three forces (lift, drag, and weight) that act on a glider; and finally, the four forces that act on a powered airplane. Because aerodynamics involves both the motion of the object and the reaction of the air, there are several pages devoted to basic gas properties and how those properties change through the atmosphere.
Interactive Educational (IE) Software for Aeronautics. A collection of little programs from NASA Glenn. Recent advances in computing speed, storage capability, and operating systems for personal computers and small workstations have enabled the development of a group of interactive flow solvers for education or preliminary design. Each application employs classical, one-dimensional inviscid analysis techniques to model a specific flow problem. All of these packages use a graphical user interface for interactive input and immediate display of output results. All of the software is available for free and runs on a wide variety of platforms. The original programs used X-based graphics and ran on Unix workstations(including Linux for the PC). Some of these programs are currently available for Windows PC's or as Java applets. The Java applets may be run on any platform using your browser and require no download or installation. All of the packages will soon be available as Java applets.

ANDECS (Analysis and Design of Controlled Systems) is a multi-objective design automation system which supports computational experimenting in control synthesis, dynamic system simulation, -analysis, and -optimization. Strict functional modularization with neutral object-oriented data- and model interfaces allows a flexible configuration of application tasks. This modularity also guarantees side-effect free functional extensions of the entire software system. ANDECS makes use of the 'engineering operating system' RSYST which provides an engineering database system and a user interface with macro facilities which can be driven either by graphical or command inputs. Numerical basis is the long-time improved control-engineering numerics library RASP. ANDECS integrates: CONTROL (Linear systems analysis and synthesis: Analysis and synthesis methods for linear dynamic systems like linear simulation, frequency response, calculation of poles and zeros, synthesis by pole placement, LQG or H-infinity, model-order reductionà). MATHLAB (Matlab and mathematical utilities: Basic mathematical methods like matrix computation using the Matlab syntax; modules for e.g. signal interpolation by splines, FFT, or root finding of nonlinear functions; also, a process communication module serves as a link to commercial MATLAB). SIMULATE (Dynamic systems simulation: Simulation environment for nonlinear, event-driven dynamic systems, including linearization and calculation of stationary solutions). GRAPHICS (Interactive result visualization: Standard diagrams like 2-D line, Bode, Nyquist and root locus diagrams. Special diagrams like parallel coordinates to visualize multiple optimization criteria including run-time result visualization and algorithm animation). OPTIMIZE (Multi objective optimization: Multi-objective parameter and trajectory optimization within a design environment, where the design history is recorded on an automatically evolving database, for backtracing as well as branching of the design process).

EXERCICES AUTOMATISME
Commande des systèmes non-linéaires, le point de vue des systèmes plats. L'ingénieur qui veut commander un système doit résoudre --entre autres-- deux problèmes fondamentaux : d'une part, générer des trajectoires de référence (problème en boucle ouverte) ; d'autre part assurer le suivi, i.e., la stabilisation autour de ces trajectoires (problème en boucle fermée). Les systèmes réels étant (presque) tous non-linéaires, l'utilisation d'une approximation linéaire au premier ordre (cf cours d'Automatique) n'apporte pas de réponses performantes à ces deux problèmes. L'objectif n'est pas d'enseigner une théorie générale de la commande non-linéaire --qui d'ailleurs est très loin d'exister à l'heure actuelle-- mais de présenter pour une classe de systèmes (fréquents en pratique) une démarche systématique reposant sur les techniques de réduction de modèle (méthodes de perturbations) et de changements de coordonnées non-linéaires. Le cours sera illustré par des exemples physiques très concrets ; en particulier, des études de cas sur ordinateur (simulations avec les logiciels Matlab/Simulink) permettront de se confronter --ludiquement !-- à la ``réalité" et de tester la validité des méthodes proposées : suppression du ballant sur une grue de chantier, avion à décollage vertical en vol stationnaire,véhicule faisant un créneau.

BEAMS/POUTRES:

Beam 2D Stress Analysis. Stress and deflection analysis software for mechanical, structural, civil and architectural designers. It provides instant, detailed analysis of statically indeterminate and determinate beams under in-plane static bending. Can analyze a simple cantilever or the most complex multi-span beam. In both cases it is equally easy and quick. Its intuitive and straightforward interface enables even occasional users to operate the program without referring to the manual. Building on the experience of serving a user base of over 5,000 professionals. Evaluation download. When installed for the first time, Beam 2D will automatically initiate a one-time trial license of 30 executions (i.e. the program can be started up to 30 times) to let you fully evaluate its features. While the program is running, you can analyze as many beams as you wish with no limitations - all program features are enabled. Once the trial license expires the program will not run unless the permanent license is obtained.
BEAM. Free. This simple program uses finite element method to calculate forces, moments and support reactions for continuous beams. Play this program by adding a support, a load, or additional beam sections and see how the shear and moment diagrams interact. Version 2.0 (for licensed users only) can also calculate spring reactions.

Beer and CFD - what a delightful combination. Technology Settles Longstanding Debate: Do Bubbles in a Glass of Guinness Go Down?.Learn why beer bubbles go down and not up. Admittedly a little off the main topic of the web site - beer flows rarely involve shocks as found in gasdynamic flows - but still fun. The research team simulated the motion of the bubbles using FLUENT computational fluid dynamics software.
Boundary Layer Applets (Virginia Tech).The motion of most fluid flows of engineering interest is completely described by the Navier Stokes equations. Except in very simple situations, however, these equations are too difficult to solve. At the beginning of the 20th century Ludwig Prandtl proposed a division of the problem to make it more tractable. He hypothesized that viscous effects (associated with the most troublesome terms in the Navier Stokes equations) are only important in a thin region immediately adjacent to a solid surface, termed the boundary layer. Here the velocity reduces rapidly to zero at the surface (the no-slip condition). As long as this region remains thin then a number of approximations can be made that greatly simplify the equations. This idea has turned out to be an extremely powerful one, to the extent that a huge number of engineering flow calculations today are performed by combining an inviscid solution for the outer flow with a viscous boundary layer solutions to provide the flow near the body. The present applets implement several different boundary layer calculation methods. Along with the Vortex Panel Method Applet (or another inviscid solver) they can be used to obtain complete flow solutions of the type envisaged by Prandtl.

Ideal Flow Machine. Designed for students learning elementary ideal flow. The term 'Ideal flow' describes the way in which a fluid (liquid or gas) moves when the effects of compressibility and viscosity are negligible. Ideal flow is often the first type of fluid motion that student engineers and scientists study, because it is the simplest. Large parts of the flows past ships, submarines, cars and light aircraft are closely ideal. This applet is designed to give students an environment where they may experiment with and visualize elementary two-dimensional ideal flows and thus better understand them. The following description assumes the reader has had some theoretical introduction to this subject (e.g. as given by J. J. Bertin and M. L. Smith, Aerodynamics for Engineers, Second Edition, Prentice Hall, 1989, or for more advanced readers Karamcheti K, " Priciples of Ideal Fluid Aerodynamics", 2nd edition, Kreiger, 1980). However, this does not mean that you have to understand this stuff to use and enjoy the applet. Flow around a porous flat plate with blowing. .

Hane - Our 8 Step Method for Creating a CNC Program . There are hundreds of ways to program a CNC machine to machine the same workpiece - and all may produce the same finished part. But, in addition to creating the cutting program, many other factors need to be resolved to be able to machine the workpiece. There are workholding questions, cutting tool questions, machining conditions as well as the machining process that will be programmed. As there are hundreds of ways to program a part, there are many different ways to resolve the above questions. We have tried to create a step by step procedure below that may assist you in creating a process to resolve the questions that need to be answered to create a CNC program.

Hane - Circle Milling - Like a Professional ! In this article, we're going to take you step by step through a program creation to mill a circle using the "loop in - loop out" method which takes the cutter from the center into the side of the hole using an arc move - then cuts completely around the hole - then loops back to the center using another arc move. This type of cutting gives a real nice finish in the hole, helps maintain size a little better and leaves no tool mark at entry or exit points.

Milling in the “Hot Zone”. Within specific industry segments, most machining is done within a given range of feedrates. The optimal range is what we refer to as the “hot zone,” the range where we aren’t just productive, but where we are highly productive. This is the range where the longer profit margins are made. This is the “hot zone.”

Numerical Control BCL Standards Association. NCBSA is an organization comprised of users and suppliers of EIA/ANSI 494 software and hardware. Originally called the BCL Users Group, the organization was formed in 1984. Later the name was changed to better reflect the makeup of the members and its activities. The NCBSA primary mission is to promote the use of EIA/ANSI 494 (BCL) and to assist in it's continued development. The acronym "BCL" has changed in meaning from "Binary Cutter Location" to "Basic Control Language". Historically, CLdata has been produced in a proprietary format that depended upon both the programming system and the computer platform on which the part program (CLdata) was produced. This CLdata was, and is, essentially "part oriented" and machine independent. In order to control a particular machine, the CLdata had to be tailored or postprocessed into the particular machine control data (MCD) for a particular machine. This tailoring or postprocessing was, and is, typically accomplished by a separate computer program called a postprocessor. A new, innovative approach, beginning in 1975, has led to the BCL standards we use today.

Composites Short Course. A short introduction to laminated composites, Assumptions, 3-d Orthotropric Assumption, 2-d Assumption, Which constants do we specify and how do they relate to stiffness (or compliance)? What about ply angle? What’s a stacking sequence? Usually, we want to know the combined response of laminate! We can define resultant forces and resultant moments! Using stress/strain relations, ply angle, thickness and strain assumption, we get the celebrated ABBD matrices. The formulae for ABBD are... Now we have everything we need to relate applied moments and forces to strains and curvatures. Look at some cases of E-glass/epoxy .125 plies.What if I want a composite to act like metal in-plane? Quasi- or Pseudo- Isotropic Composites.What if I want a plate to bend when I pull it? What if I want a really stiff plate in x-direction, that has to act like metal in-plane? What about more complicated structures? How do I make a composite? What happens during a cure? Room temperature cure composites.

How Strong is Fibreglass? A composite material, such as fibreglass, consists of two distinct materials, a fibre (glass) and a binder or matrix (polyester) each with its own mechanical properties such as stiffness and strength. When the two materials are combined to make a composite, the mechanical properties depend not just on those of the two materials being mixed, but on the relative amount of each material - we use the term volume fraction to describe the relative volume occupied by the fibre or reinforcing material - the shape and size of the reinforcement and its orientation with respect to the loads that are to be applied to the composite. Let's take the simplest of all composite materials, one made up from identical continuous fibres which are all aligned in the same direction and are to be subject only to loads applied parallel to the axis of the fibre. There are two properties that are of interest, the stiffness (Elastic Modulus) and the strength (Tensile Strength).

Software/Composites. Over the past ten years or so, a number of computer programs have been produced within the Composites and Coatings Group (Materials Science Department at Cambridge), covering topics in the fields of composite materials, surface coatings and a range of processing operations. The programs treat phenomena such as stress development, thermal expansion, interfacial debonding, creep, heat flow, solidification etc. Some of the programs were written to implement relatively complex analytical solutions and others to establish numerical solutions, using finite difference methods. The solutions concerned are not readily obtainable via simple sets of analytical equations, such as could be implemented using a hand calculator. In some cases, they could be obtained using standard commercial software packages, but not without considerable investment of time and resource. The Composites and Coatings Group has made compiled versions of some of these programs available to any interested party via this Web site. For each of the programs in this library, a published reference ("Guide to programs") is available giving scientific details. The programs concerned are all quite straightforward to use. In general, they cover simple situations and most relate to 1-D or 2-D geometries.

Product Design: Sketch Modeling. A lecture from the Mechanical Engineering Department at MIT. Sketch models are approximate 3 dimensional models. One can think of a sketch model as a 3-dimensional sketch, sometimes referred to as a soft model. The models are used just like concept sketches--to both explore and gain insight into preliminary ideas, and to communicate ideas. Specifically, they facilitate the exploration of aspects not accessible through 2-dimensional paper sketches. They can be used to demonstrate primary elements in a product and perform simple experiments. They can be made very quickly and are quite cheap. Typically, many sketch models are made in the process of developing a product. This lecture presents a variety of techniques that will be helpful when you make sketch models of your designs. The lecture begins by briefly introducing some common materials used to make sketch models. Then, techniques for working with the materials are outlined.
Product Design : Visual Modeling . A lecture from the Mechanical Engineering Department at MIT. Visual models are non-operational models that appear to be the real product. These models are used for the evaluation of visual, tactile, and other aesthetic user-interface qualities. This eclectic lecture presents a variety of modeling techniques and illustrates skills that will help you make visual models of your designs. The lecture begins by briefly introducing some common materials used to make visual models. Tools for shaping these materials are described and techniques, such as cutting and shaping, are demonstrated. Methods to create models that look realistic are explained, including building complex shapes from simple forms and finishing techniques from sanding to painting. Finally, a number of quick tips for effective mock up displays, parting lines, and hinges are described.

FLUENT. CFD Flow Modeling Software. Preprocessing is the first step in building and analyzing a flow model. It includes building the model (or importing from a CAD package), applying a mesh, and entering the data. We supply two preprocessing tools, GAMBIT and TGrid . Third-party preprocessing tools can also be used. After preprocessing, the CFD solver does the calculations and produces the results. We provide three general-purpose solvers: FLUENT and FIDAP, and POLYFLOW . FLUENTis used in most industries. FIDAP and POLYFLOW are also used in a wide range of fields, with emphasis in the materials processing industries. Postprocessing is the final step in CFD analysis, and involves organization and interpretation of the data and images. All Fluent software includes full postprocessing capabilities. Third-party postprocessors can also be used. Application-Focused Packages. We also provide three software packages which are highly-focused design and analysis tools tailored to specific application areas: Icepak is for electronics cooling.

Propellers: JavaProp - Design and Analysis of Propellers . JavaProp is a relatively simple program, which is based on the blade element theory. The blade is divided into small sections, which are handled independently from each other. Each segment has a chord and a blade angle and associated airfoil characteristics. The theory makes no provision for three dimensional effects, like sweep angle or cross flow. But it is able to find the additional axial and circumferential velocity added to the incoming flow by each blade segment. This additional velocity results in an acceleration of the flow and thus thrust. Usually this simplified model works very well, when the power and thrust loading of the propeller (power per disk area) is relatively small, as it is the case for most aircraft propellers.

WEBMAP. WEBMAP2 is a MS-Windows program providing graphical indications of engine crankshaft alignment based on measurements of crankshaft web eflections, recently revised to include automatic data acquisition, English / Metric operation, and other features. Developed by Southwest Research Institute's Mechanical and Fluids Engineering Department for the Gas Machinery. Research Council. The use of crankshaft deflection measurements to assess the alignment of large stationary engines is common practice in industry. At best, these measurements are tedious and the analytical tools to collect, view, and process the data have been generally lacking. The WEBMAP software program was developed by SwRI and GMRC in 1992 to provide simplified input of crankshaft geometry and the systematic collection of the web deflection measurements. Web deflection measurements taken from all throws of a reciprocating machine can be used to infer displacements of individual journal bearing centers from their true end-to-end crankshaft centerline. These measurement can then be stored and retrieved for analysis, trending, and simplification of later measurements. Once collected, the raw data and shaft deflection may be viewed in tabular or graphical form. The user may then make trial adjustments (when needed) to the model to develop the set of adjustments necessary to realign the crankshaft. WEBMAP is prevented from printing or saving files until it is paid for and registered.

FMEA - Failure Mode and Effect Analysis: Software Links.
FMEA: Product Design and Process Improvement with Failure Mode and Effects Analysis ( FMEA - Qi²).

FMEA - Failure Mode and Effects Analysis is an easy to use and yet powerful pro-active engineering quality method that helps you to identify and counter weak points in the early conception phase of products and processes. The structured approach makes it easy to use and even for non-specialist a valuable tool. The benefits obtained encompass by large the investments in time and resources to execute the analysis. On this site you will find information and links to various aspects of FMEA: FMEA books, FMEA literature and references, FMEA research, FMEA training, services and consultancy, FMEA standards, FMEA software, ... The FMEA Info Centre also has a download-page where you can download specific FMEA documents (FMEA tutorials, FMEA standards, ...). Finally the FMEA Info Centre has a discussion list to allow FMEA-users to share ideas and knowledge about FMEA. Link to FMEA download page (where you find: "Incorporating a user-focused failure models and effects analysis-like technique into the design of safety critical systems", "Example of FMEA worksheet with severity, probability and detectability tables.", "Introduction to FMEA", "Short introduction to FMEA from Fraunhofer Institut Produktionstechnik und Automatisierung", "Risk –Informed Regulation of Marine Systems Using FMEA by LT Robb Wilcox, P.E.

", "Free FMEA software (Excel based)", "Guidelines for conducting a Failure Modes and Effects Analysis (FMEA) on GSFC spacecraft and instruments".
FMECA stands for Failure Mode, Effect and Criticality Analysis. It is also known under the acronym FMEA (Failure Mode and Effect Analysis). FMECA is a technique used in RCM (Reliability Centered Maintenance) to find the optimum mix of the different types of maintenance. FMECA is a well known technique. Several plants have used it and lots of them have made small adaptations to it. This spotlight will present an FMECA which can be done relatively quickly. Other types of FMECA exist, but are a lot more time consuming. (OBS: en français: "AMDEC - Analyse des Mode de Défaillance, de leurs Effets et de leur Criticité "

FElt . FElt is an open source system, freely available, for finite element analysis. The current version of FElt knows how to solve linear static and dynamic structural and thermal analysis problems; it can also do modal and spectral analysis for dynamic problems. FElt's element library currently contains fourteen elements. The FAQ contains some additional information about what what kinds of problems FElt can solve as well as some information about expandability if you think you'd like to hack on FElt for your own purposes. A user can access FElt's capabilities through several different interfaces. The three most important are felt, the basic command-line application for solving FE problems given a standard FElt input file, burlap, our powerful, interactive, scripting environment that combines the flexibility of Matlab-like programs with FElt's finite element know-how and velvet, the full-featured CAD like pre- and post-processor that uses the X Window System for a graphical environment. All three applications use an intuitive, ASCII based syntax for problem definition. This powerful syntax allows you to substitute analytic functions in place of numeric values (sin(60) instead of 0.866025) and even more importantly allows for time-dependent forcing and boundary conditions to be specified as analytic functions of time or in the more traditional fashion as a series of discrete time, magnitude pairs. This feature makes it quite easy to specify a wide range of functions.

MIL-HDBK-5H - Military Handbook - Metallic Materials and Elements for Aerospace Vehicle Structures. (46M, 1600 pages !!! ). This document is intended primarily as a source of design allowables, which are those strength properties of metallic materials and elements (primarily fasteners) that are widely used in the design of aerospace structures. These metallic materials include all systems potentially useful in aerospace and aircraft applications, including those involving reinforcing components. This document also contains information and data for other properties and characteristics, such as fracture toughness strength, fatigue strength, creep strength, rupture strength, fatigue-crack propagation rate, and resistance to stress corrosion cracking. The use of this type of information is not mandatory. Those properties presented as design allowables are listed as A-, B-, or S-basis values (see Section 1.4.1.1 for definition of basis). Data for other properties are presented as typical. The materials included in this document are standardized with regard to composition and processing methods and are described by industry or government specifications. In addition to the properties of the materials and elements themselves, there are contained herein some of the more commonly used methods and formulas by which the strengths of various structural elements or components are calculated. In some cases, the methods presented are empirical and subject to further refinements. Any further expansion of information on element behavior in MIL-HDBK-5 will emphasize those material characteristics needed to assist the design function. Where available, applicable references are listed at the end of each chapter. Download a zipped Adobe Acrobat (PDF) version of MIL-HDBK-5H. (36M)

CALTRANS: California Departement of Transportation. Earthquake Engineering >Computer Programs . DOS Programs. NFOOT The NFoot computer program may be used to analyze an existing pile footing or analyze a retrofit footing with new retrofit piles and/or tie-downs. The column may be placed anywhere on the footing (i.e. unsymmetical pile layout). The footing is analyzed separately in the longitudinal and transverse directions. Axial loads and bending moments are applied at the column centroid about the applicable axis. The column centroid is located at X & Y coordinates (0,0). The footing is assumed to be infinitely rigid with no flexural deformation of the footing considered. For a given footing rotation, a neutral axis is assumed and pile deflections are calculated. These deflections are used to determine pile reactions from nonlinear force-deflection curves modeled as piece-wise linear curves. The program allows separate compression, tension and lateral force-deflection curves for the existing piles and retrofit piles. The program iterates on the neutral axis location until the sum of the vertical forces are zero. The applied moment is then determined by summing the pile reactions about the applicable footing axis. YIELD The Yield program will analyze, check or design concrete columns for biaxial bending and axial load y the ultimate strength theory. Computation of ultimate strength is based on the satisfaction of the applicable conditions of equilibrium and compatibility of strains. The program uses the "Bridge Design Specification" of California Department of Transportation (Caltrans). The program is based on "Analytical Investigation of the Seismic Response of Long, Multiple Span Highway Bridges," by W.S.Tseng and J.Penzien of U.C. Berkeley - EERC 73-12. CONC The Conc program will design or check reinforced concrete sections using the "Bridge Design Specification" of the California Department of Transportation. The cross section may have a rectangular or flanged shape. Up to eight layers of reinforcing steel may be used and will be in either tension or compression depending on the applied loads. The bars may be input as single bars or bundled two vertically or two horizontally. The program determines the area of tension steel required to resist applied dead load and live load moments. FOOT This program designs or checks pile and spread footings using the Bridge Design Specifications of the Caltrans, hereafter referred to as the Code. The types of applied loads are service loads (SER), factored loads (FAC) and earthquake loads (CA). The loads are combined into groups (GR) and cases (CA) as defined in section 3.22 of the Code Axial loads and bi-axial bending moments are applied at the footing centroid. The footing is assumed to be infinitely rigid and the pile loads or footing pressures are calculated from the static equations of equilibrium. For pile footings, the program has an option to neglect tension in the piles and redistribute the forces to the piles in compression. For spread footings, the program considers uplift and calculates a line of zero pressure (neutral axis). Input parameters include the footing dimensions, depth of earth cover, sizes of reinforcement, column end conditions (FIX or PIN), footing material properties, pile data, spoil data, and a minimum footing depth. In the design mode, the minimum footing depth is automatically increased in 1” increments until the one-way shear, punching shear and flexure requirements of the Code are satisfied. The program considers shear reinforcement. Serviceability requirements of the Code are also checked. For pile footings, a table of maximum and minimum footing pressures is printed, along with the location of the line of zero pressure. A table of final results is printed containing the depth of footing required and the amount of top and bottom flexural reinforcement required.

CALTRANS: California Departement of Transportation. Earthquake Engineering >Computer Programs . DOS Programs. NFOOT The NFoot computer program may be used to analyze an existing pile footing or analyze a retrofit footing with new retrofit piles and/or tie-downs. The column may be placed anywhere on the footing (i.e. unsymmetical pile layout). The footing is analyzed separately in the longitudinal and transverse directions. Axial loads and bending moments are applied at the column centroid about the applicable axis. The column centroid is located at X & Y coordinates (0,0). The footing is assumed to be infinitely rigid with no flexural deformation of the footing considered. For a given footing rotation, a neutral axis is assumed and pile deflections are calculated. These deflections are used to determine pile reactions from nonlinear force-deflection curves modeled as piece-wise linear curves. The program allows separate compression, tension and lateral force-deflection curves for the existing piles and retrofit piles. The program iterates on the neutral axis location until the sum of the vertical forces are zero. The applied moment is then determined by summing the pile reactions about the applicable footing axis. YIELD The Yield program will analyze, check or design concrete columns for biaxial bending and axial load y the ultimate strength theory. Computation of ultimate strength is based on the satisfaction of the applicable conditions of equilibrium and compatibility of strains. The program uses the "Bridge Design Specification" of California Department of Transportation (Caltrans). The program is based on "Analytical Investigation of the Seismic Response of Long, Multiple Span Highway Bridges," by W.S.Tseng and J.Penzien of U.C. Berkeley - EERC 73-12. CONC The Conc program will design or check reinforced concrete sections using the "Bridge Design Specification" of the California Department of Transportation. The cross section may have a rectangular or flanged shape. Up to eight layers of reinforcing steel may be used and will be in either tension or compression depending on the applied loads. The bars may be input as single bars or bundled two vertically or two horizontally. The program determines the area of tension steel required to resist applied dead load and live load moments. FOOT This program designs or checks pile and spread footings using the Bridge Design Specifications of the Caltrans, hereafter referred to as the Code. The types of applied loads are service loads (SER), factored loads (FAC) and earthquake loads (CA). The loads are combined into groups (GR) and cases (CA) as defined in section 3.22 of the Code Axial loads and bi-axial bending moments are applied at the footing centroid. The footing is assumed to be infinitely rigid and the pile loads or footing pressures are calculated from the static equations of equilibrium. For pile footings, the program has an option to neglect tension in the piles and redistribute the forces to the piles in compression. For spread footings, the program considers uplift and calculates a line of zero pressure (neutral axis). Input parameters include the footing dimensions, depth of earth cover, sizes of reinforcement, column end conditions (FIX or PIN), footing material properties, pile data, spoil data, and a minimum footing depth. In the design mode, the minimum footing depth is automatically increased in 1” increments until the one-way shear, punching shear and flexure requirements of the Code are satisfied. The program considers shear reinforcement. Serviceability requirements of the Code are also checked. For pile footings, a table of maximum and minimum footing pressures is printed, along with the location of the line of zero pressure. A table of final results is printed containing the depth of footing required and the amount of top and bottom flexural reinforcement required.

ADAPT-FELT . Computer program for the Friction, Elongation and Long-Term stress loss computation of tendons in prestressed structures. For a given tendon geometry and stressing specification, the software computes the stresses along the tendon length. Tendon geometry can be selected from the program's pre-defined profiles, or, in the case of irregular tendons, the geometry can be input through tendon coordinates. The immediate loss computation includes the friction and seating of tendon (wedge draw-in). The long-term losses include creep, shrinkage and relaxation in steel. The computations are based on the recommendations of ACI Committee 423. The software handles both bonded and unbonded systems.

Transient Conduction in a Sphere with Convective Boundary Conditions. Why do you need a thermometer to cook a turkey? Common sense tells us that when you put a cold turkey into a hot oven it takes time for the center of the turkey to heat up sufficiently to cook the meat. Why do you burn your mouth when you eat pizza? Although the crust has cooled enough for you to pick it up, the sauce and cheeze below the surface of the pizza are still very hot. The general problem: The analysis described on this page provides a simple mathematical model for these everyday problems. The details of these two situations are rather complicated: the ``material'' has very nonuniform thermal properties, both heat and moisture are being exchanged with the surroundings, and the initial temperature is not uniform. ....

TRIBOLOGY:

An On-Line Information Resource: Almost every item of machinery has moving parts, bearings, gears, slides, seals and many others. The successful operation of moving mechanical equipment is dependent on the smooth running and long life of these parts. It is research in the field of tribology that has paved the way for reliability and longevity in industrial machines. Lists: Conferences, Jobs, Journals, ImEechE Design data guides, etc.
Center for Surface Engineering and Tribology (CSET). Surface failure resulting from rubbing is a critical problem that inhibits the development of key components in advanced engines, turbines, manufacturing processes, magnetic recording systems and micro mechanical systems. In order to develop advanced components for these applications, it is necessary to understand and control basic friction, wear, and lubrication processes at the sliding interface. Surface engineering and tribology involve the basic phenomena of surfaces in relative motion. Tribology Links (ACADEMIC SITES. ARTICLES, JOURNALS, AND MAGAZINES. COMMERCIAL ORGANIZATIONS.
