双硬度靶对球形弹丸的防护性能
Anti-Penetration Performance of Double Hardness Target Impacted by a Spherical Projectile
摘要
Abstract
Ballistic experiments and numerical simulation were adopted to analyze the anti-penetration performance of double hardness explosively welded steel/aluminum plates penetrated vertically by a spherical projectile .A 14 .5 mm diameter smoothbore gun was used to launch the spherical steel projectile with a diameter of 6 mm ,and the finite element code LS-DYNA3D with the coupling algo-rithm of finite element and smoothed particle hydrodynamics (FE-SPH ) was applied to simulate the penetration process .The effects of thickness and strength of the explosively welded plates on the anti-penetration performance and damage mechanism were analyzed .The results show that the damage mechanism of the steel front layer is shearing and plugging and that of the aluminum rear layer is pro-longing deformation .For a two-layer steel/aluminum plate ,the anti-penetration performance is the worst when the thickness ratio of steel and aluminum plate is about 2/3 .The numerical simulation results are well agreed with the experimental ones ,so the FE-SPH method can predict the anti-penetration performance of two-layer explosively welded plates well .关键词
