摘要
对传统的Hopkinson压杆试验装置进行了改进和完善,除了用于材料的动态压缩以外,还能进行动态拉伸、绝热剪切、裂纹扩展速度测定、动态断裂韧性测试等.本文介绍了几种试验方法的基本原理,并给出了试验结果.
The traditional experimental apparatus of Hopkinson pressure bar is improved. Besides the dynamic compression testing, the new apparatus can be used to carry out experiments for dynamic tensile testing, adiabatic shear testing and measurement of crack propagation rate and dynamic fracture toughness. The fundamental principles of testing are introduced and testing results are given.
