Fatigue Damage in Metals: Numerical Methods-Based Approaches provides readers with detailed and easy-to-implement simulation and modeling techniques for predicting, analyzing, and ultimately mitigating the effects of fatigue damage in metallic materials. The book is divided into three sections, the first of which covers various fatigue loading simulation techniques, the second looking at modeling methods for predicting and analyzing the cyclic behavior of metals, and the final section which discusses fatigue damage operators, criteria, and methods and also includes two chapters dedicated to case studies. It addresses variable amplitude loadings, yield surfaces-based models for cyclic plasticity simulation, fatigue crack imitation and propagation related to microstructure, probabilistic approaches, and more. New criteria and numerical techniques for analyzing the initiation and propagation of cracks are included, as are raw data, algorithms, and codes that can be put into immediate use.
