Voids Development in Metals: Numerical Modelling

The article is a continuation of two previous review papers on the fracture mechanism structural metals through nucleation, growth and coalescence voids. In present paper, literature numerical modelling void nucleation development has been reviewed. scope work does not include porous material models their implementation. As part discussion initiation, around second phase particles as an effect discontinuity crystal structure were discussed separately. basic cell models, finite element method (FEM) periodically distributed particles/voids based results observations actual microstructure materials have characterised. Basic issues related to application cohesive approach in considered. A separate issue characteristics atomistic simulations peridynamic modelling, which developed recent years. Numerical approaches voids are described, with particular emphasis influence stress state strain localisation. conclusions from simulation presented, pointing contribution FEM understanding microstructural phenomena leading ductile fracture.
