球形弹丸作用下钢/铝爆炸复合靶的抗侵彻性能
Anti-penetration performances of aluminum-steel explosively-welded composite plates impacted by spherical projectiles
摘要
Abstract
A 14. 5-mm slip chamber gun was used to shoot the spherical steel projectile with the diameter of 6 mm to penetrate into steel-aluminum or steel-aluminum-steel explosively-welded plates. The LS-DYNA3D software was applied to simulate these penetration processes, and the tie-break model was used to describe the interfaces between the explosively-welded layers. The effects of the different combinations of the explosively-welded plates on the anti-penetration performances and the damage mechanism were analyzed. The results show that when the total thickness of the plate is constant, the anti-penetration performance of the three-layer plate is better than that of the two-layer plate. For the two-layer plate, the optimized thickness ratio of the two layers is about 2 : 1. At this ratio, the two-layer plate, of which the front layer is steel, the rear layer is aluminum, has the best anti-penetration performance. The damage mechanism of the front layer is shearing and tucking. The damage mechanism of the rear layer is prolonging deformation (when it is aluminum) and petal deformation (when it is steel). And the simulated results are in good agreement with the experimental ones, so the tie-break model can reflect the effect of the interlayer combination on anti-penetration performances.关键词
