Thermoelastic fracture mechanics with regularized hypersingular boundary integral equations

This paper is concerned with thermoelastic fracture mechanics, in three-dim ensional 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 mechan ics (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 i sothermal LEFM computer code called BES is extended in this work to include thermoelastic terms. Some numerical results are presented from this new co de. (C) 1998 Elsevier Science Ltd.
