Abstract
The stress intensity factors for cracks in three-dimensional, thermall y stressed structures are computed by using the boundary element metho d. While many boundary and volume-integral-based formulations are avai lable for the treatment of thermoelastic problems in solids, the prese nt analysis is based on a recently developed boundary-only formulation . The accuracy of the solutions in the present work is improved by usi ng special elements at the crack front that accurately model the varia tion of displacement, temperature fields and singularity of traction, flux fields.
