heal.abstract	The T-criterion, based on the extrema principles of the components of SED, considers separately the particular character of the dilatational, T//v, and distortional, T//D, components of the total SED, T. This was achieved by calculating the variation of T//v along contour lines of constant T//D represented by contours of constant equivalent stress, sigma //e. The maximum of T//v calculated along a conveniently selected contour of sigma //o-stress defines the eventual crack initiation angle, theta //0, for the particular contour, where the (T//v//m//a//x plus T//D) attains a critical value for impending fracture. For the accurate prediction of fracture characteristics (angle theta //0 of fracture and fracture stress, sigma //c// infinity ) in ductile materials exact elastic-plastic stress fields are needed at the vicinity of the crack tip. A comparison of theory and experiments indicated that the T-criterion may be formulated as well by LEFM for cleavage-type cracks.	en
