The effects of inclusion distribution, size and triaxiality of the imposed stress state on void nucleation within a two dimensional, plane strain framework were analyzed. Results showed that the effective void nucleation stress was approximately a linear function of the overall hydrostatic tension with a coefficient of 0.40-0.44 for regular distributions and 0.25-0.35 for random distributions. The dependence of effective void nucleation test on a simple scalar measure of clustering was also suggested.
