| Abstract |
In the previous research on the steel-aluminum composite structure [1, 2], our research
group explored the influence of various parameters on the anti-penetration performance, and came to the conclusion that there is an inflection point and the optimal thickness ratio, etc. On this basis, this paper adopted the method of combining experiment and numerical analysis to study the anti-penetration performance of the steel-aluminum composite structure at the same surface density. Ballistic impact experiments were carried out on steel and aluminum composite target plates under different equal surface density and thickness ratio, and LS-DYNA finite element model was established for simulation experiments, which verified the effectiveness of the numerical model. The influence of three fragment parameters on the anti-penetration performance of the composite target plate under a surface density of 5 g/cm2 was investigated, and the change of the inflection point (the minimum antipenetration performance) was observed. The conclusion was drawn that the inflection point of the percentage of energy dissipation of the cubic and cylindrical fragments under different densities appeared when the thickness ratio of the target plate was 0.418, while there was no inflection point for the spherical fragment.When the mass/velocity ratio and length/diameter ratio were changed, both the cubic and cylindrical fragments showed inflection points at 0.305 and 0.418. The target plate had better anti-penetration performance for the high-speed and low-mass fragments. The effects of fragment density and mass/velocity parameters on the target plate penetration ability were significantly greater than that of the length/diameter ratio. |
