英文摘要 | In this paper a phase-field formulation based on an extended F-criterion (the normalized strain energy release rate criterion) is proposed to simulate tensile-compressive-shear rock fractures. By applying the F-criterion, the phase-field crack-driving energy decomposition is determined by a direction search which maximizes the local fracture dissipation. In compressive-shear states, the computation is supplemented by an explicitly expressed confinement-dependent mode-II fracture energy release rate, and the cracking angle is determined by both the fracture energy and strain states. The hybrid formulation and alternate minimization algorithm are adopted for the numerical examples in this paper. Fractures for rock and rock-like specimens subjected to compression demonstrate the ability of the present model in capturing tensile-compressive-shear rock fracture behaviors. |
