... of the damage evolution. Macroscopic damage and plasticity are characterized by their microscale counterparts, e.g., the pressure-sensitivity factor for the classical Drucker-Prager yield criterion is explicitly related to the friction coefficient governing stick-slip events. A significant benefit...
