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…
