Mesoscopic damage and fracturing of heterogeneous brittle rocks based on three-dimensional polycrystalline discrete element method
Rock heterogeneities often control microcracking on the grain scale and therefore the
mechanical behavior of the rock on the macroscale. We therefore studied the fracture …
