A simple model capable of reproducing all of the experimental results known for the MRL 38 mm diameter shaped charge is described. The basis of this model is the original analytical work of F'ugh, Eichelberger and Rostoker and the more recent work of Hirsch, and of Carleone, Jameson and Chou. The three phenomenological constants required by the model are found by fitting to data from the BRL 105 mm diameter unconfined shaped charge. The model is then used to calculate the jet velocity gradient and the collapse angle versus time for the MRL standard charge. Good agreement has been found with recent experimental results.
