Rock drilling is the process of penetrating and crushing rocks, which is characterized by the low rate of penetration (ROP) and drilling rate because of the amount of cuttings that remain in the drilling environment and the thermal stresses generated

Anisotropy in rock is among the important parameters that should be considered in studying fracture toughness and fracture mechanisms. Acoustic emission is one of the methods applied to investigate fracture mechanics and how microcracks grow in rock

A computational code has been developed based on finite-volume method (FVM) to investigate fluid flow-through rough-walled rock fractures during shear processes, considering evolutions of aperture and contact area with shear displacement. In the code
