Abstract:

This report describes a simple model of the MRL Materials Research Lab 38 mm shaped charge which is based on the analytical work of Pugh, Eichelberg and Rostoker. The modified Richter equation is used to estimate the bending angle and then the steady state Taylor equation is used to calculate the initial liner speed Vo. The inverse velocity gradient effect is included by allowing the liner to have a velocity-time curve of the type described by Carleone, Jameson and Chou. The three phenomenological constants required for this type of approach are found by fitting the model to data from the BRL 105 mm unconfined shaped charge, and the model is then used to calculate the jet velocity gradient and the collapse angle versus time for the MRL shaped charge. Good agreement with recent experimental results is found. The report concludes by discussing the utility of the model for various parametric studies, and an illustration is given by calculating the dependence of jet tip velocity on cone half angle.
