dc.description.abstractMicrofractures and discontinuities are the common structural features of the rock mass lead initiating and developing the brittle fractures in rocks. Fracture toughness is an intrinsic material property for the pre-exist cracks initiate fracture development and play a significant role in brittle fracturing. The Cracked Chevron-Notched Brazilian Disc (CCNBD) samples were tested to determine the fracture toughness of monsonite and sandstone samples. Since conducting fracture toughness tests are quite hard compared with the Brazilian test, the tensile strength can be determined by using the tensile fracturing parameters of rocks. Moreover, stress analysis obtained from the Extended Finite Element (XFEM) modelling confirmed a comprehensive relationship between tensile strength and tensile fracturing parameters of rocks. Based on the laboratory experiments, the tensile strength o f rocks can be used for the modelling of tensile fracturing and this will improve our understanding of rock fracturing behaviour utilising for the rock cutting and mining designs.
