Vibration fatigue Wikipedia

Vibration fatigue is a mechanical engineering term describing material fatigue, caused by forced vibration of random nature An excited structure responds according to its naturaldynamics modes, which results in a dynamic stress load in the material points The process of material fatigue is thus governed largely by the shape of the excitation profile and the response it produces
