Abstract

Abstract

In this study, to improve the penetration capability of the homogeneous long rod, a problem whose solution has hit a bottleneck, we designed a new pre-composited rod fabricated with high density tungsten alloy and high hardness tungsten carbide. It was validated through experiment and numerical simulation that our newly-designed rod can form a sharp nose shape in the steady penetration stage by cashing in on the different properties of different materials to improve the penetration capability of the long rod. Based on the experimental and simulated results, we presented a full description of the physical image of the pre-composited rod's normal penetration into a steel target, which can be divided into three sections, those of the cratering, the composited rod, and the homogeneous rod, with their theoretical models established respectively, thus obtaining the calculation model of the total pre-composited rod's penetration depth. The rationality of the model was verified by comparing it with the experiment and simulation results. The conclusions from our study are helpful for the kinetic design of weapons using the new long rod.
- high-density tungsten alloy,
- high-hardness tungsten carbide,
