适用范围：This part of BS 7448 describes a method for determining the opening mode plane strain fracture toughness KIc, the critical crack tip opening displacement (CTOD) fracture toughness and the critical J fracture toughness of metallic materials. The method uses fatigue precracked specimens tested in displacement control at rates of increase in stress intensity factor greater than 3.0 MPa·m
