The contents of this book have been carefully planned to provide both an introduction to the fundamental theory of material deformation simulation, and a comprehensive survey of the state-of-the-art of deformation modelling techniques and their application to specific and industrially relevant processes. To achieve this, leading international figures in the field of material deformation research have been invited to contribute chapters on subjects on which they are acknowledged experts. The book is arranged in four parts: Part One deals with plasticity theory, Part Two with various numerical modelling techniques, Part Three with specific process applications and material phenomena, and Part Four with integrated computer systems. The editors' goal for this book is to contribute to a greater undderstanding of numerical techniques for material deformation process modelling. The wealth of practical applications contained in the text demonstrate the tremendous potential that exists for using numerical modelling methods to increase the efficiency of industrial material deformation processes and to improve product quality, structure and reliability.
