Summary:This paper describes the contact stiffness between the surface of some materials of diffrent rough and a smooth surfaces. First, the experiments were conducted to investigate the relation between displacements and loads of steel balls from the elastic region to the plastic region of the contact pressure. Second, the experimental equation between the displacements and the loads was expressed by using the experimental results. Finally, the contact stiffness of the roughness was estimated by using the equation. When analyzing the contact of the rough surface with the smooth surface, the state of the contact on the asperities was divided into two parts: the plastic and the elastic region.
