The stress intensity factors for cracks in three‐dimensional, thermally stressed structures are computed by using the boundary element method. While many boundary and volume‐integral‐based formulations are available for the treatment of thermoelastic problems in solids, the present analysis is based on a recently developed boundary‐only formulation. The accuracy of the solutions in the present work is improved by using special elements at the crack front that accurately model the variation of displacement, temperature fields and singularity of traction, flux fields.
