Abstract
In this research, the subcritical crack growth parameters for Coconino sandstone under mode I, mode II and mode III loading were determined using a constant stress-rate test. The subcritical crack growth parameter n is approximately determined to be 37, and the parameter n is similar to each other regardless of the loading configuration. The parameter A varies with the loading configuration and the geometry. The mode II shear strength is higher than the mode III shear strength and the ratio of the mode II fracture toughness to the mode I fracture toughness is equal to 1.8.
