Cryosuction‐induced fracturing in multiphase porous materials: Numerical modeling and experimental validation

Whether naturally- or artificially-induced due to human activities, decreasing increasing the suction in multiphase-fluid-saturated porous materials can lead enormous changes their thermo-hydromechanical properties. In this, both mathematical description and numerical modeling of coupled problem present a challenging task. The following contribution considers instance related micro-cryosuction-induced fractures, which be observed saturated unsaturated under freezing conditions. This research focuses on continuum media mechanics extended by diffusive phase-field fracture method. For cryosuction-induced fractures media, water is treated as phase-change process. modeled using approach, thermal energy derives phase change and, thus, leads occurrence micro-cryosuction formation ice phase.
