The rock deformation and failure processes under uniaxial compression are a fundamental issue in mechanics. This study constructs numerical heterogeneous specimen composed of Voronoi polyhedral particles using Neper software. It examines the fracture patterns, mechanical behavior, strength granular through simulations 3-D distinct element code. findings demonstrated that number cracks escalates with increasing axial stress. rate crack initiation rises significantly when stress is approximately 57.3% peak stress, shear start to appear reaches 73.84% These specimens exhibit significant splitting damage compression, transitioning from tensile as improves. In addition, smaller internal friction angles lead more severe failures, fully developed zones are, pronounced mass?s zonal fracturing becomes.
