The interaction between cracks, as well their propagation, in single-crystal aluminum was simulated at the atomic scale by molecular dynamics method and modified embedded atom method. Further, effects of distance two cracks difference crack size on propagation mechanical properties were comprehensively investigated. results demonstrated that multi-crack is a quite complex process, which accompa...

To study the fracture characteristics and permeability change law of cracked specimens during complete stress-strain process, a mechanical model was constructed, from which different types crack initiation angles were obtained. The inclination under uniaxial compression, confining tension, influence pressure pore water on propagation rock mass investigated simulated with RFPA-Flow software usin...
