Abstract

The effect of wear on the crack propagation behavior for short cracks under fretting conditions is investigated by using numerical method. The numerical simulation effectively combines the remeshing technology with the adaptive meshing technology, and the evolution of contact force and crack length caused by wear can be considered in this study. The critical distortional elastic energy criterion is used to determine the threshold condition of short crack propagation, and the Archard equation is employed for wear simulation. The results show that wear reduces the short crack propagation rate. Furthermore, the effect of wear on the short crack propagation rate is more obvious for the shorter initial crack length.
