Stress intensity factors around an insulated crack situated parallel to the plane surfaces of an infinite elastic layer are determined. The upper surface of the layer is heated to maintain the constant temperature T_0, while the lower surface of it is cooled to maintain the constant temperature -T_0. The thermoelastic problem is reduced to that of solving a pair of dual integral equations. To solve these, the difference of the crack surface temperature and those of the crack surface displacements are expanded in a series of functions which are automatically zero outside of the crack. The unknown coefficients accompanied in the series are solved by the Schmidt method. The stress intensity factors and the strain energy release rate are calculated numerically.
