The near crack line solution for plane stress tensile crack growth in an elastic-perfectly plastic material
Abstract
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 quasi-statically 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.
