Abstract:
The compression of ceramic (corundum) tubes by the detonation products of explosives were studied experimentally and numerically. The formation of a shaped-charge flow of ceramic particles and its effect on steel witnesses targets was investigated. The tubes were produced by detonation spraying. Ceramic particles were deposited on substrates – copper tubes, which were then dissolved in a solution of iron chloride. The experiments showed a significant penetrating effect of the flow of ceramic particles. Metallographic analysis showed that during the interaction of the flow with the target, the target material was partially evaporated. Numerical analysis of the process demonstrates features of the formation of the discrete shaped-charge jet: the maximum velocity of the leading part of which was about 23 km/s, and the velocity of the main part of the jet was about 14 km/s.
Keywords:
dispersed shaped-charge jets, hypervelocity acceleration, high-modulus ceramics.
