Abstract

The near crack line field analysis method has been used io investigate into theexact elastic-plastic solutions of a mode Ⅱ crack under plane stress condilion in anelastic-perfectly plastic solid. The assumptions of the usual small scale yielding theory.hare been completely. dbandoned and the correct formulations of matching conditionsat the elaslic-plastic boundary. have been given. By, matching the general solution ofthe plastic slress field(bul not the special solution used to be adopted) with the exactelastic stress field(but not the crack tip K-dominant field) at the elastic-plasticboundary, near the crack line, the plastic stresses, the length of the plastic zone and theunit normal vector of the elastic-plastic boundary.which are sufficiently precise near the crack line region,have been given.
