This study analyzes the influence of bonded and unbonded interface conditions on the anti-penetration performance of a ceramic/metal composite target and determines the associated mechanism. The 3D finite element and 3D smoothed particle hydrodynamics simulation results revealed that a bonded ceramic/metal target exhibited better anti-penetration performance than an unbonded target, and the associated mechanism was determined. Notably, the bond strength between the ceramic and metal backplate plays an important role in the formation of the ceramic conoid, and the ceramic conoid that formed in the bonded target effectively consumed the kinetic energy of the projectile, thereby improving the anti-penetration performance of ceramic composite armor. To verify this conclusion, we also compare and analyze the anti-penetration performance of interface bonded and unbonded metal/metal composite targets. The results show that due to the absence of the ceramic conoid, the interfacial bonding conditions have little influence on the anti-penetration performance of a metal/metal composite target.

界面结合条件对陶瓷/金属复合靶材抗侵彻性能的影响
这项研究分析了结合和未结合的界面条件对陶瓷/金属复合靶材抗侵彻性能的影响,并确定了相关的机理。3D有限元和3D平滑粒子流体动力学仿真结果表明,结合的陶瓷/金属靶材比未结合的靶材具有更好的抗穿透性能,并确定了相关的机理。值得注意的是,陶瓷与金属背板之间的结合强度在形成陶瓷圆锥体中起着重要作用,并且在粘结靶中形成的陶瓷圆锥体有效地消耗了弹丸的动能,从而提高了弹丸的抗穿透性能。陶瓷复合装甲。为了验证这个结论,我们还比较并分析了界面键合和未键合的金属/金属复合靶材的抗穿透性能。结果表明,由于不存在陶瓷圆锥体,界面结合条件对金属/金属复合靶材的抗侵彻性能影响很小。
