The influence of the T-stress on the directional stability of cracks

Melin, Solveig LU (2002) In International Journal of Fracture 114(3). p.259-265
Abstract
The sign of the T-stress has been widely used for deciding whether directional stability prevails for straight cracks subjected to mode I loading under small scale yielding. However, there is little evidence for the reliability of such a criterion. On the contrary, it is shown that a local criterion is not applicable and that directional stability generally depends on body and load geometry as well as on material parameters, whereas the sign of the T-stress is totally irrelevant in most cases.
