Friction and wear of contact surfaces during rolling and sliding should be predicted precisely and then controlled well to develop hightechnology in the industry. In order to alalyze the cyclic plastic deformation in the repeated rolling-sliding contact, it is necessary to use the constitutive model for cyclic plasticity. However, there is no analysis in repeated rolling-sliding contact using the constitutive model. Recently, the first author proposed a constitutive model for metallic material subjected to cyclic loading assuming strain hysteresis dependency, using the loading function considered as the motion of the center of the loading surface. In this paper, an attempt is made to analyze the behavior of the inelastic deformation of S20C during rolling and sliding under a contact pressure sufficient to cause yielding, using a finite element method incorporated in the constitutive model. As a result, it is demonstrated that this model is effective for this kind of problem.
