Abstract
When a ductile metal is subjected to some slightly tensile or compressive mean stress, it may occur that voids experience tensile stresses in some directions but compressive ones in other directions In this case void collapse in the latter directions can be prevented through contact with the inclusions which have generated the voids, and this greatly influences void growth and subsequent coalescence This paper is devoted to the analysis of this phenomenon. From numerical simulations, one derives an approximate model for ductile metals incorporating the effects of both void shape and possible hindering of void shrinkage by inclusions.
