Plasticity criterion for porous medium with cylindrical void

Abstract : A simple Gurson-based yield criterion for porous materials with cylindrical voids in plane stress is proposed. With no adjustable parameters, it compares quite satisfactorily with recent numerical data by Francescato et al. for different porosities. It is non-analytic with respect to the porosity, and displays an angulous point.
