A practical residual decision approach which provides significant effectiveness in computational time and the stability of wear solution was proposed for analyzing the wear process with fretting fatigue cycles. The range of the incremental wear step and smoothing of total wear curve were determined by the residual decision approach. The RMS error between the computed wear curve and smoothed one obtained by law frequent filtering techniques was calculated in this approach. The changes of contact surface configuration, contact pressure and tangential surface stress with fretting fatigue cycles were discussed as a demonstrational example under the partial slip and fretting fatigue limit condition.
