A model of thermoelastic dynamic contact in conditions of frictional heat and wear

Zbigniew S. Olesiak, Yurii A. Pyryev
We have constructed and investigated a model of thermoelastic contact of solids with inertia forces taken into account, in conditions of frictional heat and mechanical wear. It has been assumed that a layer is in a relative motion with respect to a wall. During the motion the gap between the layer and the wall changes due to heat expansion of the layer. The influence of material constants, velocity and parameters of the model on the contact characteristics have been investigated. The solution to the problem has been reduced to a system of the Volterra-Hammerstein non-linear integral equations, which in turn has been solved by means of the developed algorithm. The numerical solutions have been presented in diagrams.
