Crack evolution of soft–hard composite layered rock-like specimens with two fissures under uniaxial compression

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 6,   Pages 1372-1389 doi: 10.1007/s11709-021-0772-2

Abstract: image correlation were used to study the spatiotemporal evolution characteristics of crack extension of softand hard composite laminated rock masses (SHCLRM) containing double fissures under uniaxial compressionThe effects of different rock combination methods and prefabricated fissures with different orientationsThe test results show that the damage mode of SHCLRM is related to the combination mode of rock layersHard layers predominantly produce tensile cracks; soft layers produce shear cracks.
