Fracturing porous solids with pore content (B02)

• Subject Area: Mechanics ; Applied Mechanics, Statics and Dynamics
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 327154368

We describe fracturing porous solids with arbitrary pore content by two basic ingredients, the REV-scale Theory of Porous Media and the phase-field approach to fracturing. The solid is treated as a brittle elastic material that is permeable for arbitrary fluids in the sense of a Darcian pore-fluid flow. Under hydraulic fracturing conditions, cracks will open depending on fluid pressures and solid strength, and the fluid flow in the cracked zones changes from purely Darcian to Stokean type. Interfaces between the solid and the pore fluids are contributing to hydraulic-conductivity and fracturing conditions.
