Abstract

Abstract

A void growth equation is derived for elastic-plastic deformation process by means of representative volume element (RVE). The distribution of the void number density has been numerically investigated under the condition of the same ratio of inner and outer diameters for all voids. Influences of initial damage on development of spalling damage have been indicated by analyzing the distribution of void number density, the cumulative percentage of void volume and the volume fraction of the different-seize voids.
