... in terms of fracture toughness. Two different testing methods, slow rising displacement and incremental step loading testing, were used to generate J-R curves and determine the fracture toughness. The tests were performed at 40°F in air and simulated sea water (3.5 wt.% NaCl) with applied CP of −1050 mV...
