本文介绍了45号钢、TC4钛合金及WTG05钨合金三种金属管在内部爆炸载荷下的宏观剪切断裂行为,并对此作了一些初浅的分析,提到了实验中发现的钛合金的一种反常单向性剪切起裂现象,同时发现该钨合金在爆炸应变率下表现为脆性断裂。
In this paper, macroscopic shear failure behaviors of three kinds of metal tubes, including 45 # steel, TC4 titanium alloy and WTG05 tungsten alloy, under internal blast load are introduced. Some preliminary analyzes are made on this. Some examples of titanium alloy Anomalous unidirectional shearing and rupturing phenomenon was also found. At the same time, the tungsten alloy showed brittle fracture at the explosive strain rate.
