INITIATION OF EXPLOSIVES THROUGH METAL BARRIERS.
Abstract
Two cylindrical explosive charges separated by steel discs of varying thicknesses were used in a series of tests in which one explosive charge was detonated to obtain a low order detonation wave in the explosive charge on the opposite side of the steel disc. The acceptor charge showed that as the plate thickness increased, the length of travel of the low order wave and the time to high-order detonation increased. No high-order detonation occurred where an explosive-to-metal length ratio of greater than 3:2 was used. When the highorder detonation wave traveled back through the region traversed by the low order wave the velocity showed a slight decease from stable high-order detonation velocity, but the decrease did not appear to be significant. There are some indications that an additional effect may be obtained when a high-order detonation wave is passed through a low order region; however, this part of the tests was inconclusive. (Author)
