A Multiscale Anisotropic Poroplasticity Damage Model for Cracked Solids
This work presents constitutive thermodynamic formulations for modeling poromechanical behaviors of saturated microcracked rocks. The Mori-Tanaka homogenization scheme is adopted to determine the effective properties of the matrix-inclusion system. Continuity conditions in both stress and strain energy are used to determine unknown constants. The friction criterion is formulated in terms of the macroscopic stress, the back stress and the pore pressure. The present study can improve and extend our researches along this line. A numerical prediction of true triaxial mechanical behaviors of Westerly granite is finally presented.
