... ABSTRACT: Rockbolts/rock anchors are one of primary reinforcement/support members and utilized widely in both civil engineering and mining engineering. They are generally fixed into rock mass through boreholes utilizing cement or resin-based bonding material. Therefore, their bonding strength...

... textures. Specifically, micro-structural variations in grain sizes and bonding strengths inside each layer may introduce a higher degree of anisotropy. There is a wide range of variability of laboratory-measured fracture toughness of natural rock specimens because of micro-structural textures. However...
