A Multi-Phase-Field Anisotropic Damage-Plasticity Model for Crystalline Rocks

Sun, WaiChing; Na, SeonHong

Many engineering applications, such as geological disposal of nuclear
waste, require reliable predictions on the thermo-hydro-mechanical responses of
porous media exposed to extreme environments. This presentation will discuss the
relevant modeling techniques designed specifically for such environmental conditions.
In particular, we will provide an overview of the coupling method of crystal
plasticity and multi-phase-field model designed to replicate the thermal- and rate-dependent
damage-plasticity of crystalline rock. Special emphasis is placed on
capturing the intrinsic anisotropy of salt grain in 3D with respect to damage behavior
and plastic flow by incorporating the crystallographic information of salt.
