Abstract
For a metal reinforced by hard particles full three dimensional cell model analyses are carried out to study the evolution of ductile matrix failure. As the cell model contains part of two particles, it can account for transversely staggered particles of different size, in addition to rather general multi-axial stress states. A porous ductile material model is used to describe the effect of nucleation and growth of voids to coalescence. Comparison of predictions for an isotropic hardening solid and a kinematic hardening solid is used to evaluate the effect of a metal that forms a rounded vertex on the yield surface.
