摘要：
A suitable elastic stress field near the crack line has been reasonably assumed and successful analysis has been made of a near crack line field for a quasistatically propagating plane stress tensile crack in an elastic-perfectly plastic material. A complete solution for the strain on the crack line has been obtained. It is shown that the solutions of this problem in some recent papers, by using the notch stress field as the elastic stress field near the crack line, are inappropriate.
