Study on the short fatigue crack initiation and propagation behavior of 42CrMo
Advances in Mechanical Engineering, 2022 A micro-tensile fatigue test of 42CrMo alloy steel was carried out. The result shows that the crack initiation and propagation of the material could be characterized with randomness and localization.
