Roller/ring tribo-fatigue system which is used in wear-fatigue tests as the model of wheel/rail system is considered. In this system as well as in wheel/rail system stress-strain state is defined by interaction of contact and volume deformation of one of the system elements. These loads in the roller/ring system are defined by single compressive force. Results of finite element simulation of stress-strain state of roller/ring system are presented. Significant change of contact parameters and stresses distributions in this system due to the bending of the ring comparing to the contact pair is shown.
