A Multicomponent Particle Model and Linear Fitting Calibration Method for Heterogeneous Rocks by Qifeng Guo, Ying Zhang, Xun Xi, Xu Wu, Meifeng Cai

“…The multicomponent bonded-particle model significantly improves the accuracy of three parameters: the ratio of tensile strength to uniaxial compressive strength, the friction angle, and the parameter mi of the Hoek–Brown criterion. The linear fitting calibration method provides a fast and efficient way to determine the microparameters of particles in heterogeneous rocks.…”
