摘要
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。
This paper describes the macroscopic shear fracture behaviours of three kinds of tubes (45 steel, Ti-6Al-4V, WTG05-tungsten alloy) under internally blast loading, a simple analysis has been given. A strange one-way shear cracking phenamena in Ti-6Al-4V is observed and that the tungsten alloy behaves as brittle fracture at explosive strain rates is found as well.
