Paper Title:
Study on the Crack Initiation Criterion in Fretting Fatigue of LZ50 Steel
  Abstract

Fretting-fatigue often occurs at the contact area between two materials. There exist strong stress singularity exist at the contact edge, crack usually initiation at here. In this paper, the singular stress fields near the contact edge is obtained by using commercial code ABAQUS, then, the curve fitting method is used to determine the stress-singularity order and stress-strength parameter. Finally, the criterion of fretting-fatigue crack initiation in LZ50 steel is determined by using stress-strength parameters.
