heal.abstract	In the present paper a new fracture criterion, suitable for both brittle and ductile materials, is described. The main idea of this criterion is that, whichever is the critical quantity for crack initiation, it must be evaluated along the elastic-plastic boundary around the crack-tip. On the one hand, the introduction of the elastic-plastic boundary permits the direct evaluation of the size of the, so called, 'core region', and on the other hand the yield condition can be selected properly, to describe the brittle or ductile behaviour of the specific material. Experimental results from two glassy polymers show good agreement with the theoretical predictions, especially in the case of the ductile material.	en
