Abstract
This work presents recent progress in phase-field-based fracture modeling in heterogeneous porous media. Existing algorithms that have been developed in the last years are extended to tackle three-dimensional configurations. Our solution technique is formulated in terms of a nested Newton loop that combines a primal-dual active set method (required for treating the crack irreversibility) and a Newton method to solve the nonlinear, fully-coupled PDE system. An advanced numerical test demonstrates the capabilities of our method.
