Damage and failure by dilatancy of viscoplastic rock-like materials are considered. A damage parameter is introduced which is the total energy release due to microcracking when dilatancy takes place. This is expressed with the irreversible part of the volumetric stress power. The damage parameter ca
Rock is a heterogeneous geological material that contains natural weakness of various scales. When rock is subjected to mechanical loading, these pre-existing weaknesses can close, open, grow or induce new fractures, which can in turn change the structure of the rock and alter its fluid flow propert
