Fatigue Mechanisms of Porous Rocks Subjected to Cyclic Pore Pressures: Insights from Hydro-Mechanical Phase-Field Simulations
In this work, we formulate a hydro-mechanical phase-field model to investigate the fatigue failure behavior of porous rocks under cyclic pore-pressure loading. Our phase-field model integrates pore-pressure diffusion, fatigue-induced degradation of failure resistance, and breakage constitutive laws into a unified fra...
