THE PLANE CONTACT PROBLEM OF STEADY THERMOELASTICITY TAKING HEAT-GENERATION INTO ACCOUNT

The plane steady contact problem of thermoelasticity when there is hea t generation from friction, which arises when an infinite cylindrical punch moves over the surface of an elastic half-space along its genera trix, is considered. It is assumed that heat exchange between the free boundary of the half-space and the surrounding medium obeys Newton's law, while the condition for ideal thermal contact exists in the regio n in which the solids interact. The problem is reduced to a system of three integral equations in the heat fluxes and temperature. The effec t of the thermal and mechanical properties of the cylinder and the hal f-space on the main contact characteristics is investigated numericall y. (C) 1998 Elsevier Science Ltd.
