Abstract

In order to explore the efficiency of cylindrical fragments of different materials penetrating the target in different contact gestures, the WorkBench-LsDyna software is used to simulate the cylindrical fragmentation under different working conditions, assuming that the fragment’s speed is 1800𝑚/𝑠, and the target is vertically held with different gestures. Simulation results show that when cylindrical fragments penetrate the target, the side edges first penetrates the target with the strongest penetration, and the cylindrical side penetrates the target with the worst ability; When cylindrical fragments of different materials penetrate the target, the greater the density under the same structural size, the stronger the penetration, and there is less energy loss and larger residual velocity after penetrating the target, but the impact of the structural size on the penetration of the fragment should be considered when designing the cylindrical fragment.
