EXPERIMENTAL RESEARCH ON THE FRACTURE CHARACTERISTICS OF HY-130 STEEL

Li Zhaofei; Zheng Guanghua(Qindao Institute of Architecture) (Beijing University of Aeronautics and Astronautics,Dept. of Jet Propulsion)Turner C E(Imperial College, London, UK )  
The behaviors of J-R curves and dissipation rates for side grooved deep notch three point bend test pieces of HY-130 steel with the same thickness but different widths have been studied. Crack growth occurs at limit load and the R-curves follow the pattern that wider pieces give lower curves. Analysis is made and argued that dWdis./Bda is a parameter to reflect the fracture toughness of materials.
