Rock fracture-toughness determination by the Brazilian test

Journal Article


Abstract


  • Fracture mechanics analyses on the diametral crack behaviour in a disc with diametral compression were carried out. Based on these analyses, it is proposed that a simple conventional Brazilian test, which is normally used for the determination of rock tensile strength, be applied to measure rock fracture toughness. The fracture toughness of six types of rocks are determined by the proposed method. The results compared favourably with those determined by the Chevron bending specimen method, one of the recently proposed international standard methods by the ISRM. �� 1993.
