A Simplified Model for Clayey Rocks Having a Plastic Porous Matrix
This study is devoted to a micro-macro model of plastic deformation in a clayey rock which is composed of a ductile porous clay matrix and linear elastic mineral grains. By making use of nonlinear homogenization methods with a two-step homogenization procedure, we derive a closed form expression of the macroscopic plastic criterion which accounts for the effects of pores and of mineral inclusions simultaneously. Then, a non-associated flow rule is proposed. Comparisons between the predictions of the full micro-macro model and available experimental data show that the proposed model is able to capture the main features of the mechanical behavior of the clayey rock.
