By the method of boundary integral equations, we solve the problem of stationary heat conduction and thermoelasticity for a semiinfinite body containing an elliptic crack perpendicular to its boundary in the case where the crack surfaces are kept at a certain temperature. The boundary of the body is unloaded and either thermally insulated or kept at temperature equal to zero. We study the influence of crack depth and its location on the stress intensity factor at a given constant temperature.
