heal.abstract	In this paper the crack initiation under stress-assisted diffusion is studied. Around the crack-tip a core region is developed by the stress-assisted diffusion. This core region is a strongly brittle area which depends on the sum of the principal stresses at the crack-tip and on phenomenological coefficients. Based on this assumption, the crack extension angle is determined by use of the Det.-criterion. This study is applied for various materials with different phenomenological coefficients. © 1991.	en
