The study aims on by contact analysis of a cylindrical wheel and a rail structure of I–section with considering the material properties of an elastic–plastic adhesive frictional contact. Different materials are considered for the analysis based on Young’s modulus and yield strength ratio (E/Y). The contact analysis of this model has been carried out using analysis software ANSYS. The simulation results shows that the maximum stress and strain developed at a point near by the contact edge for lower E/Y value of material and move along the center of a straight line in the contact region between wheel and rail if the E/Y value increases. The results are compared with the basic contact model and shows that good agreement for the nature of material dependence.
