Abstract: During comminution, fracture initially occurs because particles contain preexisting cracks (flaws), which propagate in response to tensile stresses generated during compressive loading. At the tip of all cracks within a loaded material, the stress is concentrated because the load cannot be uniformly distributed across the full area. In the present paper, the effects of crack inclination angle and crack length on the through-thickness mode I (KI), mode II (KII), and effective (
