Abstract

Abstract

The elastic-plastic stress distribution and the elastic-plastic boundary configuration near the crack surface region are sign ificant but hard to obtain by means of conventional analysis. The crack line analysis method was developed through considering the crack surface as an extension of the crack line. The stresses in the plastic zone, the length and the unit normal vector of the elastic-plastic boundary near the crack surface region were obtained for an antiplane crack in an elastic-perfectly plastic solid. The usual small scale yielding assumptions have been abandoned during the analysis.
