Abstract
In this contribution, the Desai hierarchical model is extended to the case of 3D elasto-plastic two-phase micropolar continuum. An unconditionally stable implicit Euler backward algorithm for integration of the constitutive relations is developed and presented in detail. The regularizing effect of the introduction of a length parameter to the classical Desai model is demonstrated by means of several case studies of single phase and two-phase porous media.
