Javier Bonet is a Professor of Engineering and Head of the College of Engineering at Swansea University, Director of the Welsh 'Sêr 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.
