【摘要】 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。为了证明空心杆的动态可靠性。本文用二维动力有限元法分析了空心杆的一维性。更多还原

【Abstract】 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.In order to explain the reliability of the dynamic testing with the hollow bar,we have calculated the transverse effects of the hollow bar using the dynamic finite element code.更多还原
