Fatigue and Fracture Characterization of Am60b Magnesium Alloy Morteza Mehrzadi

A research on fatigue and fracture response of AM60B magnesium alloy is presented in this book. The investigation is focused on characterization of the influence of compressive stress cycles within a given cyclic loading scenario on alloy?s crack propagation response. Fatigue crack growth rate (FCGR) of AM60B alloy subject to cyclic loadings with various stress ratios (both positive and negative) is investigated and a modified model is proposed. The investigation is continued by studying the influence of compressive stress cycle (CSC) on FCGR. Furthermore, application of an overload within an otherwise constant amplitude loading (CAL) has been studied.
