Designing engineering components that make optimal use of materials requires consideration of the nonlinear static and dynamic characteristics associated with both manufacturing and working environments. The modeling of these characteristics can only be done through numerical formulation and simulation, which requires an understanding of both the theoretical background and associated computer solution techniques. By presenting both the nonlinear solid mechanics and the associated finite element techniques together, the authors provide, in the first of two books in this series, a complete, clear, and unified treatment of the static aspects of nonlinear solid mechanics. Alongside a range of worked examples and exercises are user instructions, program descriptions, and examples for the FLagSHyP MATLAB computer implementation, for which the source code is available online. While this book is designed to complement postgraduate courses, it is also relevant to those in industry requiring an appreciation of the way their computer simulation programs work.

This book provides a clear and complete postgraduate introduction to the theory and computer programming for the complex simulation of material behavior. It will also appeal to those in industry wishing to appreciate the way their computer simulations work.

Javier Bonet is a Professor of Engineering and Head of the College of Engineering at Swansea University, Director of the Welsh 'Sźr Cymru' National Research Network in Advanced Engineering and Materials, and a Visiting Professor at the Universitat Politecnica de Catalunya in Spain. He has extensive experience of teaching topics in structural mechanics, including large strain nonlinear solid mechanics, to undergraduate and graduate engineering students. He has been active in research in the area of computational mechanics for over 25 years, with contributions in modeling superplastic forming, large strain dynamic analysis, membrane modeling, and finite element technology, including error estimation and meshless methods (smooth particle hydrodynamics). Since the book was completed, he has been appointed as Deputy Vice-Chancellor, Research and Enterprise, at the University of Greenwich. Antonio J. Gil is an Associate Professor in the Zienkiewicz Centre for Computational Engineering at Swansea University. He has numerous publications in various areas of computational mechanics with specific experience in the field of large strain nonlinear mechanics. His work covers the areas of computational simulation of nanomembranes, biomembranes (heart valves) and superplastic forming of medical prostheses, fluid-structure interaction, modeling of smart electro-magneto-mechanical devices, and numerical analysis of fast transient dynamical phenomena. He has received a number of prizes for his contributions to the field of computational mechanics. Richard D. Wood is an Honorary Research Fellow in the Zienkiewicz Centre for Computational Engineering at Swansea University. He has over 20 years' experience of teaching the course 'Nonlinear Continuum Mechanics for Finite Element Analysis' at Swansea University, which he originally developed at the University of Arizona. Wood's academic career has focused on finite element analysis. He has written numerous papers in international journals, and many chapter contributions, on topics related to nonlinear finite element analysis.
