We consider the interaction of elastic half-spaces with equal thermal distortivities in the presence of a heat-permeable medium in an intercontact gap caused by a recess on the surface of one of the bodies. Outside the gap, a perfect thermal and frictionless mechanical contact takes place between the bodies. Using the method of functions of intercontact gaps, the formulated contact problem is reduced to a singular integral equation for a derivative of the height of the gap, which is solved analytically, and to a Prandtl-type singular integro-differential equation for the difference of temperature of the surfaces in the region of the gap, for the solution of which we propose an analytic-numerical approach. Plots illustrate the influence of load and the thermal conductivity of the filler on the temperature difference between the edges of the gap, contact stresses, heat flows, and longitudinal strains between the half-spaces.
