Crack propagation characteristics and mechanism of energy evolution in intermittent externally fissured sandstone
Geostress environment and fracture distribution both exert important influences on the mechanical properties and failure modes of fissured rock masses. Laboratory test results are presented here to simulate particle flow code (PFC) in externally double-fissured sandstone samples. Mechanical responses of confining pressure and rock bridge angle on stress-strain curves as well as macroscopic damage and fracture propagation in these samples were studied in order to elucidate energy dissipationdoi:10.21203/rs.3.rs-29394/v1 fatcat:t6k2cu7tyfgllmrawkx6xtzho4
