Micro‐Macro Fracture Mechanism, Energy Evolution and Damage Constitutive Model of Rock‐Like Materials With Heterogeneous Parallel Double Flaws Under Triaxial Compression
To investigate the effects of flaw geometric heterogeneity on the mechanical behavior of rock under triaxial compression, this study examines sandstone‐like specimens containing parallel double flaws, systematically evaluating the coupled effects of multiple parameters including flaw spacing and the apertures of pr...
