This title demonstrates how to develop computer programmes which solve specific engineering problems using the finite element method. It enables students, scientists and engineers to assemble their own computer programmes to produce numerical results to solve these problems. The first three editions of Programming the Finite Element Method established themselves as an authority in this area. This fully revised 4th edition includes completely rewritten programmes with a unique description and list of parallel versions of programmes in Fortran 90. The Fortran programmes and subroutines described in the text will be made available on the Internet via anonymous ftp, further adding to the value of this title.

Following the highly successful previous editions, this 4th edition contains programs and subroutine libraries fully updated to Fortran95, which are freely available on the Internet. A wide variety of problem solving capabilities are presented including structural analysis, elasticity and plasticity, construction processes in geomechanics, uncoupled and coupled steady and transient fluid flow and linear and nonlinear solid dynamics. A major new feature is the inclusion of parallelised programs, using MPI, which enable parallel processing of all types of finite element analyses. Performance evaluation shows that these programs make efficient use of parallel hardwares ranging from supercomputers to clusters of PCs.
Key features:

A clear outline of modular programming philosophy.
More than 60 programs covering a wide range of problems in engineering and science.
Results display using PostScript files.
Exercises for students to solve.
A simple but powerful parallelisation strategy.
These improvements all contribute to a more comprehensive book with a wide appeal. It will be of particular interest to students and practitioners in the application of finite element methods; to undergraduates and postgraduates in civil, mechanical and aeronautical engineering (stress analysis and fluid flow problems); to applied mathematicians and physicists (solution of partial differential equations); and to engineers in all of the above fields.

Computational Welding Mechanics (CWM) provides an important technique for modeling welding processes. Welding simulations are a key tool in improving the design and control of welding processes and the performance of welded components or structures. CWM can be used to model phenomena such as heat generation, thermal stresses, and large plastic deformations of components or structures. It also has a wider application in modeling thermomechanical and microstructural phenomena in metals. This important book reviews the principles, methods, and applications of CWM.

The book begins by discussing the physics of welding before going on to review modeling methods and options as well as validation techniques. It also reviews applications in areas such as fatigue, buckling, and deformation, improved service life of components, and process optimization. Some of the numerical methods described in the book are illustrated using software available form the author that allows you to explore CWM in more depth.

Computational Welding Mechanics will be a standard work for welding engineers and all those researching welding processes and wider thermomechanical and microstructural phenomena in metals.

This book presents a modern viewpoint of welding thermomechanics and provides a unified and systematic continuum approach for engineers and applied physicists working on the modelling of welding processes. The theory presented includes developments in the areas of welding thermodynamics, thermoplasticity and numerical methods. The book describes the calculation of thermal stresses in welding structures, the theory of heat conduction in welding, and the basic equations of thermoplasticity, then applies the concepts to solutions of thermoplasticity problems and to thermal stresses in arc welding, laser welding, spot welding, electroslag welding and friction welding.
