Scope: This standard specifies the test methods for fracture toughness, crack tip opening displacement, J-integral and resistance curves of homogeneous metallic materials subjected to quasi-static loading. The sample has a gap, and the fatigue method is used to prefabricate the crack, and the test is carried out under the condition of slowly increasing the displacement.
