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.
