Wear phenomenon concerned with two sliding contactors is simulated by the nonlinear finite element method. Holm-Archard wear law is used to build model for mild oxidation and delaminating wear. A modified wear law is implemented to calculate wear profile, which is affected strongly by the initial surface topology. The node-to-segment contact element is applied to obtain contact stresses and sliding distance between two contact bodies. A simple geometry update process is implemented to test if more accurate variables about the system could be obtained. Two illustrative examples of indentation and pin-on-disk test show the ability of the proposed method to simulate wear phenomenon.
