Improved Analytical Shaped Charge Code: BASC
Abstract
The work of many researchers has been combined to produce a simplified, analytical, computer code to address the shaped-charge problem. This code named BASC (BRL Analytical Shaped Charge) is programmed in the FORTRAN language. BASC utilizes a modified version of the metal acceleration model of M. Defourneaux of France to account for both the final liner velocity and its acceleration history. The BASC code accurately predicts jet-tip velocity and treats the buildup of the massive lead pellet, for both heavy confined and unconfined charge geometries. Calculation of the massive lead pellet has traditionally been difficult and is accomplished in BASC by including time dependent acceleration and material compressibility in the region of the liner near the apex of the conical liner. The BASC code includes the jet formation theory of Pugh, Eichelberger, and Rostoker; the shaped-charge penetration theory of DePersio, Simon and Merendino for penetration-standoff curves; and the piece wise penetration of Defourneaux for hole profiles. BASC enables parametric investigations of shaped charge problems with relatively small amounts of computer time since the code is basically analytic. Results from the BASC code are compared to experiments as well as to more sophicated hydrodynamic computer codes. The report documents BASC, including the equations utilized, necessary empirical relations, FORTRAN listing of the program, selected problem examples and comparison with experiments.
