摘要
本文利用示波冲击试验，对船用９２１Ａ钢动态断裂韧性的测试方法进行了研究。采用小角度冲击标定法对裂纹动态起裂点进行了标定。
In this paper, the dynamic fracture toughness measuring method for 921A shipbuilding steel is studied by 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.
