Abstract

Abstract

With the development of hypervelocity kinetic energy weapons, the mechanism of long rod hypervelocity penetration into concrete target was a research highlight. To study the penetration mechanism and the crater law of long rod hypervelocity penetration into concrete, two kinds of long rods, TU1 and Q235, hypervelocity penetration into concrete with initial velocity of 1.8−2.4 km/s were experimented. Dimensional analyses of crater diameter and crater volume were performed based on the experiment data from this paper and references. Prediction formula of crater depth was derived from the bowl shape contour of crater section. The crater size of hypervelocity penetration was obviously larger than that of low and medium velocity penetration, and so the crater phase was non-negligible during the penetration mechanism researches. The length of the long rod was severely shortened until the long rod was completely eroded, the radius of the hole was obviously larger than that of long rod, and these results can be used to verify that the mechanism of long rod hypervelocity penetration into concrete was semi-fluid penetration. At the same time, it can be seen from the experimental results that the length of the long rod was the most important parameter affecting the penetration depth. The penetration depth increased with the increase of the length and density of the projectile, but was not affected by the strength of the long rod.
