对钛合金圆管进行了内部爆炸加载实验,用高速分幅摄影记录下其动态变形、断裂过程,对回收破片在光学显微镜下进行了观察,探讨了钛合金圆管在动载荷作用下的变形、损伤和破坏机理.实验结果表明:钛合金圆管表现为绝热剪切破坏 The inner tube of the titanium tube was subjected to an explosion loading test. The dynamic deformation and fracture process of the titanium alloy tube was recorded by high-speed radiography. The recovered fragments were observed under an optical microscope. The deformation of the titanium alloy tube under dynamic load was discussed , Damage and failure mechanism.The experimental results show that the titanium alloy tube shows adiabatic shear failure
