Abstract: Based on the basic equations and continuity conditions, the configurations of the near-tip fields for a plane stress tensile crack in a perfectly plastic material have been studied in details in this paper. It is shown that the general solution of the near-tip fields contains, an elastic region, and the stresses are continuous. Specially, it is reduced to the solution which, is given by Hutchinson (1968) as the elastic region degenerates into an elastic kernel.
