Abstract

The paper deals with a mathematical description of instability and localization in rocks through a multi-scale modeling strategy with coupled multiphysics. We adopt a homogenization approach to work out an effective description of microscopic phenomena at the continuum through defining a Representative Volume Element (RVE). The role of hydro-mechanical coupling in the transition from an otherwise initial diffuse state to a localized state can be investigated through the gradual degradation of the kinematics due to micro-fracture formation.
