This book presents studies on the plasticity, failure, and damage behavior of materials and structures under monotonic and cyclic loads. Featuring contributions by leading authors from around the globe, it focuses on the description of new effects observed in experiments, such as damage under cyclic loading. It also proposes various simulation models based on different approaches and compares them with tests, taking scaling aspects into account.
