An Attempt to Use the Results of Microtomographic Studies of the Surface After the Period of Operation in the Numerical Analysis of Wheel-Rail Contacts

摘要

During the contact of two bodies, their interaction causes an increase in stress and thus an increase in surface energy. Therefore, this energy, depending on the type of material, can cause physicochemical changes in it, which in turn lead to the phenomenon of decohesion. In order for the phenomenon to occur, it must be exceeded the limit of strength of the material is usually the yield point.
