摘要
在SHPB实验数据分析的基础上,提出了用柱锥形弹丸代替纯柱形弹丸研究材料的动态卸载。用所提出的方法对LF6铝材的动态加、卸载响应进行了实验研究,结果表明:柱锥形弹丸可以有效地延长入射脉冲的卸载段,可用来研究材料动态卸载行为。
A new method is proposed to study the unloading behavior of materials, with which the conventional cylinder projectiles in SHPB tests are replaced by cylindercone ones. With this method, the dynamic loading and unloading responses of the LF6 aluminum are investigated. The results show that the cylindercone projectile is an effective way to study the unloading behavior of materials, due to its ability to prolong the unloading phase of the incident impulse.
