Abstract

In this contribution

the development of a continuum phase-field model of brittle fracture for poroelastic solids is presented. The phase-field approach treats the discontinuity at the discrete lower-dimensional crack interface in a continuous diffusive setting. The system of equations is treated numerically by a monolithically coupled Newton-Raphson iterative-incremental solution strategy to be a scientific open-source finite element software OpenGeoSys. This contribution presents the governing equations along with details of said numerical implementation together with verification examples and perspectives for model application.
