Abstract
The effect of explosive detonation wave shaping on the shape and velocity of EFP's are described in this paper. Hydrocode modeling and range testing of warheads with embedded wave shapers of varying diameter were investigated. The range tests consist of a set of experiments of a Comp-B loaded warhead/liner configuration with imbedded polyvinyl chloride buffers that range in diameter from 0 to 25 mm. Flash radiographs showing projectile geometry and velocity are compared to results of hydrocode modeling. Simulations of the explosive detonation wave propagation around the inert wave shaper are modeled using the programmed lighting time with Huygens shadow-surface HE burn method and the beta burn method. The hydrocode calculations are compared to the x-ray silhouettes and recovered EFP's from the range tests. Variations in EFP length, diameter, mass and velocity are correlated to the diameter of the wave shaper.
