My new conference paper titled with Phase-field modeling of mixed-mode fracture in rocks with discontinuities: From laboratory scale to field scale has been accepted for presentation in the 55th U.S. Rock Mechanics / Geomechanics Symposium. This work is collaborated with Yuan, Prof. L.N.Y Wong, and my dear supervisor, Prof. Jinhyun Choo. Sincerely thanks for their great contribution!
In this paper, we use the recently developed double-phase-field model to simulate the mixed-mode cracking behaviors in both laboratory- and field-scale rocks. Simulation results show that the double-phase-field model can well capture the cracking patterns of rock materials in different scales. These results further indicate that the double-phase-field model can be applied to simulate practical engineering problems with high accuracy.
