A Nonlinear Hoek–Brown Criterion for Bedded Rock with Brittle–Ductile Transition
The conventional Hoek–Brown (H–B) failure criterion does not explicitly account for the combined effects of anisotropy and high confining pressure on rock strength. In bedded rocks, anisotropic mechanical behavior arises from the orientation-dependent weakening induced by bedding planes, which breaks the stress symmetr...
