Survivability Analysis for Impacting Warheads with Shear-Control Grids

Abstract

Pearson's shear control method of fragmentation control has been successfully employed in a variety of bombs and warheads and has potential application for impacting warheads. In this study we have investigated the response of a grooved warhead case to impact loads by using the finite element code HONDO II. The characteristic response of the case segment containing the groove is the appearance of two linearly shaped regions of yielding emanating from the groove location. The effect of a shear-control grid on the survivability of a warhead depends on the grid location and on the groove depth.
