This paper is concerned with thermoelastic fracture mechanics, in three-dimensional linear elasticity, using hypersingular boundary integral equations (HBIEs). The HBIEs are regularized by employing modes of deformation (or “simple solutions”). In addition to rigid-body and linear displacement modes, which have been used before for isothermal linear elastic fracture mechanics (LEFM), a new mode is employed here. This new mode is a thermal one in which the body is elevated to a uniform temperature but fully constrained (i.e., zero prescribed displacements) on its bounding surface. An existing isothermal LEFM computer code called BES is extended in this work to include thermoelastic terms. Some numerical results are presented from this new code.
