In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, …

Fatigue is a slow cycle-number-dependent irreversible process of plastic deformation when a material is under cyclic loading. It is a progressive and localized type of structural damage. …
