Abstract:

The BRLSC code is a modified version of the HELP code developed for the purpose of predicting phenomena associated with the performance of shaped charges. During the process of modifying HELP to enable it to handle shaped charge problems, a number of additions and changes were introduced. The resulting differences between HELP and BRLSC fall into two basic categories. The first category includes the necessary additions to enable the code to generate shaped charge problems, treat explosives, simulate a slip surface between the liner and the explosive, and insure realistic jet formation. These additions were specifically required by the shaped charge application. The second category consists of changes made to improve the way in which free surface cells are handled, to allow the thin liner to move through the grid without becoming distorted, to increase the reliability and stability of calculations, and to decrease the cost of running problems. As the result of these additions and changes, most of the subroutines in BRLSC have been changed substantially from the original HELP version. However, since most of the logic involved is similar to that employed in HELP, users familiar with HELP should have no difficulties with BRLSC.
