We study the thermoelastic behavior of a heterogeneous bimaterial with interface crack whose faces are in contact at the ends under the action of compressive forces and a homogeneous heat flux. The problem of thermoelasticity is reduced to a system of singular integrodifferential equations for the temperature jumps and displacements on the crack faces. This system is solved for the case of a thermally insulated crack. The changes in the zone of contact of the crack faces are analyzed for a bimaterial formed by stainless steel and nickel alloy. The distribution of contact pressure over the crack faces is found and the dependences of the crack height and the length of the contact zone on the compressive forces and heat flux are determined.
