A Poromechanics-Based Framework for Fully Coupled Reactive Transport and Geomechanics in Porous Rocks
Fan Fei, Yifan Yang, Aleksander Zibitsker +4
Mineral precipitation and dissolution in rocks alter pore structure, stress, and hydraulic properties, producing tightly coupled chemo-hydro-mechanical processes that are central t…
A phase-field model for quasi-dynamic rupture nucleation and propagation of in-plane faults
Fan Fei, Md Shumon Mia, Ahmed E. Elbanna +1
Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of…
Crack opening calculation in phase-field modeling of fluid-filled fracture: A robust and efficient strain-based method
Fan Fei, Jinhyun Choo
The phase-field method has become popular for the numerical modeling of fluid-filled fractures, thanks to its ability to represent complex fracture geometry without algorithms. How…
A phase-field model for hydraulic fracture nucleation and propagation in porous media
Fan Fei, Andre Costa, John E. Dolbow +2
Many geo-engineering applications, e.g., enhanced geothermal systems, rely on hydraulic fracturing to enhance the permeability of natural formations and allow for sufficient fluid…
Extended Barton-Bandis model for rock joints under cyclic loading: Formulation and implicit algorithm
Fan Fei, Jinhyun Choo
In this paper, the Barton-Bandis model for rock joints is extended to cyclic loading conditions, without any new material parameter. Also developed herein is an algorithm for impli…
A phase-field model for quasi-dynamic nucleation, growth, and propagation of rate-and-state faults
Fan Fei, Md Shumon Mia, Ahmed E. Elbanna +1
Despite its critical role in the study of earthquake processes, numerical simulation of the entire stages of fault rupture remains a formidable task. The main challenges in simulat…
Phase-field modeling of rock fractures with roughness
Fan Fei, Jinhyun Choo, Chong Liu +1
Phase-field modeling -- a continuous approach to discontinuities -- is gaining popularity for simulating rock fractures due to its ability to handle complex, discontinuous geometry…
Double-phase-field formulation for mixed-mode fracture in rocks
Fan Fei, Jinhyun Choo
Cracking of rocks and rock-like materials exhibits a rich variety of patterns where tensile (mode I) and shear (mode II) fractures are often interwoven. These mixed-mode fractures…
A phase-field model of frictional shear fracture in geologic materials
Fan Fei, Jinhyun Choo
Geologic shear fractures such as faults and slip surfaces involve marked friction along the discontinuities as they are subjected to significant confining pressures. This friction…
A phase-field method for modeling cracks with frictional contact
Fan Fei, Jinhyun Choo
We introduce a phase-field method for continuous modeling of cracks with frictional contacts. Compared with standard discrete methods for frictional contacts, the phase-field metho…
