Abstract
Analyzed in this work is a semi-infinite crack that grows slowly in a steady-state. The assumed constitutive relation for the material permi ts strain hardening and softening as it is damaged in time. Four disti nct regions divided angularly are identified for the asymptotic expres sions of the quasi-static crack-tip stress field. They refer to materi al degraded in front of the crack; undergone elastic unloading; reload ing of degraded material; and material completely exhausted in its loa d carrying capacity.
