Abstract

A computer-aided analyzing methed was developed for determining the fracture toughness of rock by means of ISRM methods. Fracture toughness tests were conducted on Westerly granite using the short-rod (SR) specimens, and the results were evaluated, utilizing the program. A comparison indicated that the fracture toughness value determined by the computer-aided system agrees well with that obtained from handwork. Based on the crack growth resistance curve, the fracture toughness considering its nonlinearity was successfully determined.
