摘要

Depleted uranium alloy (DU ) is one of the most widely used material for long rod kinetic energy penetrator. The kinetic energy penetrators undergo exceedingly dynamic loading during launch and penetration. Therefor, it is important to study the dynamic properties of DU alloys for penetrator. In this paper,the dynamic properties of four kinds of DU alloys made in China, subjected to high-strain-rate and high temperature, were investigated with apparatus of split Hopkinson bar. The test data were treated, and the constitutive models of the DU alloys were developed. The experimental results indicat that the stress increases with strain rate increasing and decreases with temperature increasing at the same strain. It means that DU alloys possess obvious effects of strain and temperature.
