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 1000s to over 10,000s. 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.
