Abstract

A more reasonable crack line solution for a mode II crack under plane stress condition, as well as a mode II crack under plane strain condition in an elastic- perfectly plastic material has been obtained in the present paper. The definition of the small scale yielding in the present paper is different from the usual definition. The assumption of the usual small scale yielding that the plastic zone makes the crack tip elastic field to move a distance along the crack line has been abandoned. 1 Introduction By using the near crack line analysis method, Guo and Li [1][2] obtained the near crack line elastic-plastic field for a mode II crack under plane stress condition and a mode II crack under plane strain condition respectively in an elastic-perfectly pla
