Motivated by experimental observations, we carry out a numerical analysis of the two-stage crack growth under fretting fatigue by using an efficient and accurate boundary element method. To start with, the variation of stress field during a loading cycle is analyzed. Various values of friction coeff

Fretting frequently challenges the integrity of structures exposed to fatigue loading. The mechanics of the fretting fatigue loading must be understood in order to analyse what are the important parameters in the crack growth process of fretting fatigue. Mode I stress intensity factors of cracks per
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components. Depending on fretting and fatigue loading conditions, crack nucleation and possibly crack propagation can be activated. T
From previous investigations of the mechanisms of both fracture and fatigue crack propagation, the static fracture model proposed by Lal and Weiss may be thought as reasonable for describing fatigue crack propagation in metals at both low and interm~iate stress intensity factor ranges AK. Recent pro
