Analysis of the Concave-Convex Contact of Cylindrical Bodies

An analysis of concave-convex contact of two conform cylindrical bodies that are loaded with radial force is presented in the paper. It is known that a stress concentration is produced as the result of the contact of cylindrical bodies, where the critical point is placed under the surface of the body in contact pressure zone. Such area reprersents a potential risk of the initial crack appearance in material. Adequate experiments were performed on photoelastic model. Contact of the same contact pairs was simulated using two numerical methods: finite element method and pressure elements. Obtained results provide the basis for determination of the amplitude and position of maximum equivalent stress depending on the degree of conformity of cylindrical bodies in contact.
