Rolling Contact Problems for Plastically Graded Materials
Andrzej Myśliński , Andrzej Chudzikiewicz
AbstractThe paper deals with the numerical solution of thermo-elastoplastic wheel-rail rolling contact problems including friction, frictional heat generation and transport across contact surface. Two-material rail model is assumed, where Young’s modulus of a rail material near the rail surface is dependent on depth of the rail. The heat flow is governed by the heat conduction equation. The equilibrium state of this contact problem is described by the coupled hyperbolic variational inequality of the second order and a parabolic equation. Numerical examples are provided and discussed.
