A comparison is made between yield loci derived from the yield function and those determined from the finite element results at different void volume fractions.

Although some damage models have been proposed for many years, the initiation of ductile macrocracks of metal under complicated stress states can not be appropriately predicted; the reason for this condition is that deformation in fact dissipating ductility of metal is not taken as the starting poin
