Abstract

This paper is devoted to numerical modeling of plastic behavior of porous rocks in both drained and undrained conditions. Based on the experimental data, we propose a new plastic model based on relevant micro-mechanical results, by considering plastic shearing and pore collapse processes. The effect of porosity on the macroscopic plastic strength is explicitly taken into account. A specific plastic hardening law of the solid matrix is identified. The concept of effective stress is used for accounting for the effect of pore fluid pressure on the plastic deformation process. The proposed model is verified against drained and undrained triaxial compression tests performed on two typical rocks.
