Multiscale pore damage evolution and self-inhibition mechanism in rock after dynamic impact: a coupled statistical constitutive model integrating loading effects

Multiscale pore damage evolution and self-inhibition mechanism in rock after dynamic impact: a coupled statistical constitutive model integrating loading effects

Impact disturbance, scanning electron microscopy, nuclear magnetic resonance, and triaxial compression tests were carried out to reveal the damage evolution law of rock after different numbers of impacts. The relationship between the energy spectrum area and porosity was determined. Combining the We...
