| Abstract: | In this paper, the dynamic fracture toughness measuring method for 907A shipbuilding steel is studied through instrumented Charpy impact test. The test with low blow angle of the pendulum is carried out to detect dynamic crack initiation point, and the influence of crack geometry on dynamic fracture toughness is investigated. |
