HYPERVELOCITY IMPACT OF RODS ON FINITE TARGETS

Abstract

An analytical study has been performed concerning the impact of end- oriented aluminum and iron rods against aluminum plates of various thicknesses at velocities of 4.6 and 6.1 km/sec (15,000 and 20,000 ft/sec). A hydrodynamic model was used in these analyses, utilizing the two-dimensional particle-in-cell code to provide numerical solutions. Plots of these solutions show the development of the shock wave systems in the rods and the target plates, and the resulting plate perforation and loss of rod length. Equations are developed relating the amount of rod loss to the quantities characterizing the impact configuration, e.g., impact velocity, material density, target thickness. (Author)
