Abstract

In this investigation, a conservative integral based on the Betti reciprocal principle is employed to obtain stress intensity factors for a bimaterial notch in which the body is subjected to a thermal load. The bonded materials are linear elastic, isotropic and homogeneous. Real and complex singularities are considered. Because of the highly singular behavior of one of the integrals, it is carried out by a hybrid analytical/numerical scheme. The finite element method is employed to obtain displacements caused by the temperature change in the body. The conservative integral is applied to two problems appearing in the literature. Both good agreement between those results and the ones obtained here, as well as path stability for all problems is attained.
