Thermomechanical phase‐field fracture modeling of fluid‐saturated porous media

Abstract In this work, the problem of brittle fracture in a fluid‐saturated porous material is extended by considering non‐isothermal states sample. The temperature field will affect two aspects: 1) Temperature‐dependent parameters, such as elasticity modulus (E) and critical energy release rate (Gc). 2) Thermal expansion due to thermo‐mechanical volume coupling. hydraulic fracturing, we further study effect difference between injected fluid surrounding media ambient on crack behavior. modeling domain based macroscopic theory (TPM), whereas phase‐field method (PFM) applied approximate sharp edges diffusive ones. numerical implementation, coupled system partial differential equations be solved using FEM order simulate heat transition non‐crack regions.
