Abstract

Interaction of a metal-explosive assembly with a normally-incident shaped chare jet has been investigated with radiographic and oscillographic technique. Some of the significant effects associated with this interaction like detonation of explosive by impact of jet, expansion of covering metal plates, disturbance in coherence and reduction in penetration of the jet have been observed. It is found that the jet penetration in stack of mild steel plates is reduced to 30% of its blank penetration. The disturbance in the jet commences 12.3 μs after initiation of explosive and it remains for about 25 μs in the present set up.
