A Review of the Failure and Damage Forms of Metals under Cyclic Loading

The studies related to metals damage under cyclic loading as the dominant form of structural failure is reviewed. The early approaches including stress-based and strain-based as well as the later approaches of energy-based, critical plane-based and damage mechanics-based are briefed on. Recent methods including thermography, finite element, and microstructural are summarized and explained. Different phenomenon occurring under cyclic loading are explained including fatigue crack initiation, crack propagation, fretting, and buckling. This review provides insight on the underlying mechanisms of different fatigue damage types and related proposed models. In addition, it explains the different aspects of each model along with their methodology
