Secondly, a multi-scale finite element model is presented which allows the simulation of the deformation process near the surface of a rail under rolling sliding contact. It is necessary to model the roughness of the surfaces of wheel and rail to obtain a realistic deformation state which is comparable to experiments. Furthermore, the realistic stick-slip behaviour of a rolling sliding wheel along a rail is considered. Regarding these aspects of wheel/rail contact a realistic deformation picture with near quantitative amounts of plastic shear strains from micrometre to millimetre range can be predicted.
