THE BRL 7600 Version of the HELP Code

Abstract

The HELP computer code (BRLHELP) which is maintained on the CDC 7600 computers at the Ballistic Research Laboratory, Aberdeen Proving Ground, Maryland and the Ballistic Missile Defense Advanced Technology Center in Huntsville, Alabama, is described. Three shaped charge design applications, a 43 mm conical shaped charge, a hemispherical shaped charge, and an impacting copper wedge, are discussed. Input decks and selected output for each problem are listed, and results are compared with experiments. The energy formulation in the HELP code is analyzed and the cause of the unphysical internal energy values is identified.
