Abstract

This paper presents the results of a study of the dynamic compression of plastic-bonded PETN using the split Hopkinson pressure bar (SHPB) technique. The test procedure and some aspects of this technique are described. The advantages of the SHPB technique over drop-weight tests of explosives are briefly discussed. In the experiments, the strain rates were 7500–12 000 s^-1. Force–strain and force–displacement curves are obtained, and the amount of energy required to initiate explosive transformation is estimated. It is proposed to use this technique in addition to existing methods for studying the characteristics of explosives.

用分裂霍普金森压杆技术研究动态载荷下炸药的特性。

摘要

本文介绍了使用分开的Hopkinson压力棒（SHPB）技术对塑料粘结PETN进行动态压缩的研究结果。描述了该技术的测试过程和某些方面。简要讨论了SHPB技术相对于炸药落锤测试的优势。在实验中，应变率为7500–12 000 s ^-1。获得了力-应变曲线和力-位移曲线，并估算了引发爆炸转变所需的能量。除了研究炸药特性的现有方法外，还建议使用此技术。
