N2 - The problem of a circular shaped crack lying in a homogeneous, isotropic, elastic-perfectly plastic plate is investigated. The plate is subjected to a load at infinity such that plastic zones develop at the tips of the crack which in turn are subjected to uniform direct stress. Based on the Dugdale model and the complex variable technique developed by Muskhelishvili, analytic solutions are obtained. Crack opening displacements at the crack tip and plastic zone are calculated. The effect of increasing plastic zone on the ratio of the required applied load to yield stress is studied. The crack opening displacement is presented for cases of practical interest.
