Crack propagation simulation for ductile material under fretting fatigue loads using cohesive zone models

Abstract

The object of this study is fretting fatigue cracks subjected to cyclic loading both normal and tangential. The cycle cohesive zone model (CCZM) and extended finite element method (XFEM) are used to describe the fretting behaviour. The fretting fatigue damage is described with a damage evolution equation. Both the extended finite element method as well as cohesive zone models have been implemented into the commercial FEM software ABAQUS, via the user interfaces UEL and UMAT. The CCZM parameters are obtained from a material fatigue test result and fretting fatigue experiment.
