Provides the reader with well-balanced developments regarding both the theoretical formulations and finite element based numerical solution of nonlinear problems
This "extensive-coverage" role is what makes this book unique, unlike those books that consider the theoretical formulation of nonlinear problems in solid mechanics with no discussion of the numerical implementation issues, and those that consider only the finite element method
This well-balanced presentation of both theoretical formulation and numerical implementation gives the book a deserved place in the English speaking research community in computational solid mechanics, despite a number of available books exploring different aspects of this field
Provides full coverage all the main topics of interest for nonlinear solid mechanics
This volume provides insight into modelling and ultimate limit computation of complex structures, with their components represented by solid deformable bodies. The book examines practically all the important questions of current interests for nonlinear solid mechanics: plasticity, damage, large deformations, contact, dynamics, instability, localisation and failure, discrete models, multi-scale, multi-physics and parallel computing, with special attention given to finite element solution methods. The presentation of topics is structured around different aspects of typical boundary value problems in nonlinear solid mechanics, which provides the best pedagogical approach while keeping the book size reasonable despite its very broad contents. Other strong points are the exhaustive treatment of subjects, with each question studied from different angles of mechanics, mathematics and computation, as well as a successful merger of scientific cultures and heritage from Europe and the USA. The book content and style is also the product of rich international experience in teaching Master and Doctoral level courses, as well as the courses organized for participants from industry (IPSI courses) in France, and similar courses in Germany and Italy. Every effort was made to make the contents accessible to non-specialists and users of computer programs.
The original French edition published by Hermes Science - Lavoisier Paris in 2006 was nominated for the Roberval Award for University Textbooks in French.
