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 also 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 equivalent stress in modified Goodman's diagram, were analyzed under contact wear process, and the relationships between those parameters at fretting fatigue limits and the wear volume and elastic-plastic deformation were discussed.
