Abstract

In this paper, we present a micromechanical analysis of elastoplastic behavior of porous materials. The non-uniform transformation field analysis (NTFA) is used and the non-uniform distribution of local plastic strain in the solid matrix is taken into account. Comparisons with the classical Gurson's model and standard FEM solution are presented.

► The non-uniform transformation field analysis is adapted for porous media. ► Non-uniform distribution of local plastic strain in solid matrix is considered in micromechanical approach. ► Macroscopic behavior of porous media is strongly affected by non-uniform distribution of local plastic strain. ► The numerical predictions by the NTFA are in good agreement with the reference solution given by direct FEM simulation.
