Computer Modeling of a Booster in An Artillery Shell
Abstract
Results are given for computer simulation of the Army's M732 Artillery Proximity Fuze. The simulations were done in a study of the reliability of the detonation of the explosive in the artillery shell by the fuze. Because the computer code used--WONDY IV--integrates the differential equations of flow in one-dimension, a simplified model of the fuze was used. The quantity of p squared x tau was evaluated for each of the several models for comparison with experimental results found in the literature for TNT. When this quantity, which is the integral of p squared x d x tau, exceeds a value p squared x tau critical, the explosive is expected to detonate reliably. In the appendix, the example, which includes a plate of steel (stainless here), is examined extensively to show how stress waves propagate and interact in a multilayered configuration. These results should be of interest to both computer simulators of explosive events and to designers of booster hardware.
