Coupled phase-field and plasticity modeling of geological materials: From brittle fracture to ductile flow

The failure behavior of geological materials depends heavily on confining pressure and strain rate. Under a relatively low confining pressure, these materials tend to fail by brittle, localized fracture, but as the confining pressure increases, they show a growing propensity for ductile, diffuse fai...
