Experimental characterization and grain-based numerical modeling of multiscale fracture mechanisms in pre-fractured granite by Jie Guo, Guang Li, Fengshan Ma

“…For double-fractured specimens, strength peaks at a rock bridge angle of 60°, at which collinear crack alignment induces minimal resistance; (2) Three-stage AE evolution: AE activity progresses through initial compaction (minor events), intensifies during peak stress (crack coalescence), and diminishes toward post-failure stabilization; (3) Divergent failure modes: Single fractures display progressive tensile-dominated failure with localized shear, while double fractures promote abrupt tensile-shear hybrid failure; (4) Multiscale crack progression: Under uniaxial compression, microcracks nucleate at inter-mineral boundaries, propagate along intra-mineral interfaces, and escalate to rapid intra-crystalline coalescence, ultimately forming macroscopic fracture surfaces. …”
