For crankshaft bearings of automotive engines, conformability against crankshaft is one of the most important performances. In order to keep good conformability, the bearing surfaces are often coated with soft materials. To analyze elastic-plastic deformation problems of the coating under the condition of local contact points, a new technique of numerical simulation by particle method has been developed. By using the particle method, it is clarified that coating's elastic-plastic deformation influences friction force and depends on the material parameters.
