For new applications in multi-phase problems the water-induced failure mechanics for concrete based on the phase field approach is further investigated. Concrete has a highly heterogeneous micro-structure and its composite behavior is very complex. Due to that a various effects must be considered for analyzing failure response at the micro scale, e.g. modeling the solid skeleton, fluid bulk phases and their interaction. To this end, the fracture phase-field formulations is extended towards Darcy-Biot-type fluid-saturated heterogeneous porous media at micro-to-macro-scale.
