Revisiting the hydromechanical formulation of a micromechanics-based phase-field model for poro-elastoplastic media
Even for tension-dominated fracture propagation, porous materials may deform plastically adjacent to the propagating fracture. As is common for porous materials, existing phase-field models typically employ a non-associative flow rule for plasticity, and a Helmholtz free energy based on strain and fluid pressure. This...
