title = "Effect of confining stress and loading rate on fracture toughness of rocks",
abstract = "In this research, the effect of confining stress and loading rate on the fracture toughness has been investigated. The short beam compression test has been used to estimate the fracture toughness for Flagstaff sandstone. A brief theoretical analysis of the effects of confining stress and loading rate the fracture toughness is presented. This analysis considers changes to the critical fracture process zone size due to confining stress and loading rate. It is found that experimental results agree with the fracture mechanics theory. The mode II fracture toughness is found to increase with increasing confining stress and increasing loading rate.",
