High Strain Rate Response of Gun Propellant Using the Hopkinson Split Bar

Abstract

The Hopkinson Split Bar has been shown to be a useful tool to investigate the high rate response of gun propellant. The mechanical responses of M30, JA2, and XM39 propellants were measured at strain rates ranging from 1000/s to over 10,000/s. The results show that yield stress and modulus generally increase, and that yield strain decreases with increasing strain rate. Some effects of porosity and specimen size are also reported.
