heal.abstract	The directional instability of moving cracks was studied within the context of the maximum dilatational energy density, or T-criterion. To make bifurcation predictions according to the T-criterion theory it suffices to consider only the singular stress field. In this paper the stress field for a non-uniformly propagating crack under mode-I deformation was adopted. Predictions concerning both the critical crack velocity and the bifurcation angle was given. In this way, not only totally brittle fractures described previously by the S-criterion were correctly encountered, but also the results were extended to initially ductile materials where the T-criterion conserves its total efficiency. © 1985 Martinus Nijhoff Publishers.	en
