The influence of friction on the determination of rock fracture toughness
Abstract The accurate determination of fracture toughness (K Ic) in rock is of great significance to the study of rock fracture characteristics. However, the effect of contact friction in the loading process on the test results of fracture toughness is rarely considered, and the tested K Ic in previ...
