Abstract: Aims: This paper aims to obtain a high-precision numerical simulation method of fretting fatigue process by considering wear.

Methods: Continuum damage mechanics combined with wear is used to solve the fretting fatigue process, including crack initiation and propagation.

Results: Considering the wear, the maximum equivalent damage stress in the initiation stage and the stress intensity factor in the early stage of propagation are reduced. Total life results fall within the scatter bands of .

Conclusions: The numerical calculation method of fretting fatigue considering wear has high accuracy, especially when the number of cycles is large. At the same time, wear changes the geometry and stress state of the crack. Compared with the numerical method without considering wear, wear inhibits the initiation and propagation of cracks and increases the fatigue life.
