.... The roughness variation coefficient of 15% is taken as the criterion for the roughness to enter a stable state and the critical size for the stability of fracture surface roughness is 300 mm. Finally, the size effect on the fracture permeability was analysed. The size effect on the permeability of rock fracture...

The stress state of the contact is analyzed and the breakage criterion in the case of three-point contact is established based on the Coulomb-Moore Criterion. It is proved that the breakage criterion is effective. 1...
