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, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a … See more Historically, fatigue has been separated into regions of high cycle fatigue that require more than 10 cycles to failure where stress is low and primarily elastic and low cycle fatigue where there is significant … See more • 1837: Wilhelm Albert publishes the first article on fatigue.
