摘要

Since fretting fatigue often leads to catastrophic failure in components clamped together with relatively small amplitude displacements, several analysis methods have been developed to quantify fretting fatigue damage. Fretting damage analyses using crystal plasticity have potential to address the issues of accounting for inherent material microstructure heterogeneity as well as more realistic treatment of crystallographic slip in fretting fatigue. The primary focus of this study is to explore the influence of microstructure as well as coefficient of friction within the fretting fatigue boundary layer during fretting fatigue process. Crystal plasticity theory is used for nonhomogeneous finite element simulations and the results are compared to those developed by an initially homogeneous J2 plasticity theory with nonlinear kinematic hardening flow rule as well as experiments.
