Abstract
An integral formulation for computation of T-stresses along a three-dimensional crack front is presented. The mutual M-integral expressed through J-integrals (on analysed and auxiliary fields) provides sufficient information for determining T-stresses on the base of found relation between the M-integral and T-stresses. The auxiliary fields are selected to eliminate the singular terms in the asymptotic expansion of the stresses near the crack tip. Variation of the T-stress along the crack front of an edge-cracked plate is presented.
