| Description/Abstract | The results of a combined analytical experimental design of a high-explosive velocity-augmented kinetic energy penetrator are presented. The objective of the analysis is the design of a velocity augmentor and main charge case. The augmentor design must conform to restrictive volume constraints and provide maximum impulse to the main charge which, in turn, must survive the augmentor loading and penetrate the target. An explicit finite element hydrodynamic computer code, DYNA2D, employing arbitrary zoning, two-way sliding with gaps, and high explosive equation-of-state is employed as the analytical tool. High strain rate material models are used and predictions are compared to experimental deformations. Shock wave interactions in the main charge case are analyzed and a combination of shock attenuation and wave trapping is employed to reduce loads below failure limits. The final design provides maximum velocity augmentation while staying within volume constraints and maintaining main charge case integrity. Computed deformations and velocities are experimentaly verified. This design analysis method using state-of-the-art code and computer capabilities is shown to be an effective method of simplifying the design process as well as providing necessary design optimization data not previously available. |
