The wear process in a bridge typed fretting fatigue testing under a partial and gross slip conditions was analyzed using finite element method. The property of wear dispersed energy within one cycle loading was elucidated on the relationship of local contact pressure and relative slip. The behaviors of the contact pressure on fretting surface and tangential stress which change with fretting number of cycles were clarified. Fatigue life evaluation parameters, i.e., SWT (Smith-Watson-Topper) and the equivalent stress in modified Goodman's diagram, were analyzed, and the relationships between those parameters and the wear volume were discussed.
