Semi-implicit finite strain constitutive integration of porous plasticity models

Two porous plasticity models, Rousselier and Gurson–Tvergaard–Needleman (GTN), are integrated with a new semi-implicit integration algorithm for finite strain plasticity. It consists of using relative Green–Lagrange during the iteration process and incremental frame updating corresponding to a polar...
