In Part II, an approximate solution of the first exceedance time of a specified of ductility are presented. In this paper, a cumulative plastic deformation process defined as the sum of absolute value of individual (positive and negative) plastic deformation, was developed. For elastoplastic structures, new approximate analytical results are presented for the probability distribution of the cumulative plastic deformation, the first exceedance time of a specified level of them, and they are compared with results by the Monte-Carlo technique.
