Abstract
Thermal stresses around a crack that lies in an elastic layer sandwiched between two dissimilar elastic half-planes are examined under uniform heat flow. Surfaces of the crack are assumed to be thermally insulated. 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 in the series are solved by the Schmidt method. The stress intensity factors are calculated numerically.
