MECHANISM OF FRETTING FATIGUE

Fretting fatigue is one of the most important phenomena for inducing a dramatic reduction of fatigue strength and consequently, of unexpected failure accidents. There are numerous works on fretting fatigue. The object of this paper is to clarify fretting fatigue mechanism based on the vast amount of research work. A fretting fatigue crack is initiated at the highest point of tangential force on a contact surface in the very early state of fatigue life. The tangential force is the dominant factor in enhancing crack initiation and propagation and hence, in reducing fatigue strength. Further studies on short crack and mixed-crack growth behaviour in fretting fatigue are required.
