Fracture toughness tests based on the R-curve method using the unloading compliance calibration technique were conducted under the condition of a simulated crustal environment of a geother-mal reservoir (confining pressure 18 MPa, maximum temperature~350°C). The results obtained indicate that a significant reduction of both the elastic modulus and fracture toughness was observed with increasing temperature, and a single linear relationship was obtained between the fracture toughness Kic(J) and the elastic modulus E. In order to interpret the Kic(J)-E relationship, a model was proposed using stress-strain-opening displacement at a crack tip based on the fracture process zone.
