A Comparison Between the Eulerian,Hydrodynamic Computer Code (BRLSC) and Experimental Collapse of a Shaped Charge Liner.

摘要

The Ballistic Research Laboratory Shaped Charge (BRLSC) code is a two-dimensional, hydrodynamic, elastic - perfectly plastic, finite - difference, Eulerian numerical technique developed to simulate the collapse process of a shaped-charge liner. This code is one of a family of HELP codes. The results from the BRLSC code are compared with data from two experimental shaped-charge liner collapse studies. First, the collapse of a 43mm diameter copper liner, driven by a bare composition-B explosive, then a 105mm liner driven by an unconfined composition-B explosive. The aim of this work is to present to the munitions designer the current state-of-the-art for future research.
