The unsteady friction heating during sliding of elastic pressurized bodies

Consideration is given of a problem of contact between two elastic nonuniform bodies, one of them being a half-space and the other is bounded with on axisymmetrical round surface. The bodies have a contact due to pressurized and tangential forces. The half-space surface slides with a permanent velacity over the steady axisymmetrical surface (roughness). Contact pressure redistribution under the action of thermal energy formed on sliding with friction of the two elastic isotropic bodies is investigated. Plastic strength of this pair with friction is presented as a combination of force and temperature components of the stress tensor. The techniques for inspecting plastic deformations connected with wear is offered.
