Double-phase-field formulation for mixed-mode fracture in rocks [PDF]

open access: yesComputer Methods in Applied Mechanics and Engineering, 2020
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 usually involve microcracking and frictional sliding.
