## Abstract A threeβdimensional boundary element method (BEM) implementation of the interaction integral methodology for the numerical analysis of mixedβmode threeβdimensional thermoelastic crack problems is presented in this paper. The interaction integral is evaluated from a domain representation
In this paper the four common-used criteria for a mixed-mode crack are analysed and modified using the first two terms of Williams' stress series. In the new criteria the singular core is substituted by a plastic zone. These modified criteria take into account the influence of the plastic zone on cr
