A survey of dynamic tensile testing of materials using the hollow Hopkinson bar instead of the solid Hopkinson bar is presented, it is substantiated that the hollow Hopkinson bar has more advantages than the solid Hopkinson bar.

• 本文给出用Hopkinson空心杆代替实心杆进行材料动态拉伸性能测试实验研究。 实践证明,Hopkinson空心杆比实心杆有明显优点,我们利用了空心杆测试材料动态拉伸性能,使测试结果较实心杆有明显改进。
