This publication focuses on advanced methods for predicting and avoiding the occurrence of defects in manufactured products. It covers the major manufacturing operations, and considers conventional and new materials such as metal alloys, ceramics, composites and polymers. Topics presented include microstructural evolutions during processing induced properties in some materials, damage modelling and fracture criteria, instability analysis, specific methods for the prediction of defects and influence of defects on the integrity of structures. The book also covers a number of research trends that are still being developed, such as the development of micromechanical damage models, micromechanical analysis of fracture mechanisms and criteria, damage modelling of free surface and interface elements, and computer methods for estimation of residual strength of damaged structures or the fatigue limit.
