Ahstraet-The damage of metal alloys at the continuum level can be described by a combined process of yielding and fracture. Yielding is generally associated with excessive distortion and fracture with excessive dilatation. With the increased use of low strength alloys, gross yielding can often prece

## In this paper, crack initiation is postulated to occur in the direction along which the tangential strain energy density factor possesses a maximum value and when it reaches a critical value in the angled crack problem. As a result of its examination, we can see that this criterion is able to b
Ah&met-Sib's fracture criterion based on strain energy density, S, for mixed mode crack extension under static loading is extended to dynamic mixed mode, K, and K,,, crack propagation. Influence of the second order term, uox, which represents the non-singular constant stress acting parallel to the d
