Abstract

It is presented an integral formulation for computatin of T-stresses in a finite cracked body under static, dynamic and thermal loads. The reciprocity theorems for all three cases are utilized to find the integral formula. The auxiliary fields are properly selected to elliminate singular terms which contain stress intensity factors. A pure contour integral formula for the T-stress is obtained only in elastostatics. In elastodynamics and thermoelasticity the integral formula has a contour-domain character. For solution of a boundary value problem of a cracked body and for evaluation of variables needed in the integral T-formula the boundary element method is used. To illustrate computational capabilities numerical examples for a stationary crack in a rectangular plate
