Studies related to the energy transfer phenomena using the two dimensional slab geometry have been continue. One phase of the work deals with metal plates propelled by various composite explosive combinations consisting of two components. By utilizing explosives having different detonation rates an oblique detonation front can be induced and maintained in the lower velocity component. An enhancement in energy transfer was observed when the plate was coupled to the low-velocity element. The other phase involves the use of flat composite plates composed of a plastic-metal plate combination propelled by a single explosive. Energy transfer to the outer plate was more efficientwhen the explosive was coupled to the metallic component of the target. Penetration and hole volume data are presented for 1.100-inch base diameter shaped charges using precision copper cones with Composition B Comp B and nitroglycerin-ethylene glycol dinitrate NG-EGDN explosives. The reproducibility in the NGEGDN penetration data is observed to be very good.
