Abstract

In order to study the anti-penetration ability of target with different layered thickness, the process of long-rod projectile penetrating multi-layered target is simulated by LS-DYNA software, and the penetration depth of long-rod projectile penetrating target with different layered thickness (ratio of target plate thickness T to long-rod projectile diameter D, ratio of thickness to diameter T/D) is obtained. In addition, the simulation and experimental study of flat-nosed projectile penetrating semi-infinite target are carried out, which verified the accuracy of simulation material parameters. The results show when the rod velocity is less than 1 000 m/s, the thickness-diameter ratio of layered target with minimum penetration depth is T/D=6, and when the rod velocity is greater than 1 000 m/s and less than 1 600 m/s, the thickness-diameter ratio of the target with the best penetration resistance is T/D=5.

Key words： layer thickness; ratio of thickness to diameter; anti-penetrating; numerical simulation
