Abstract
An experimental method is developed that makes it possible to visualize the onset and spreading of damage in each layer of transparent armor. The damage development dynamics in multilayer packages consisting of four \(480\times 480\)-mm layers and eight \(300\times 300\)-mm layers is analyzed. The evolution of damage is obtained under the influence of a 12.7-mm bullet with a two-component core with a total mass of 59.2 g and a 7.62-mm bullet with a two-component core with a total mass of 10.9 g along the normal and at an acute angle in a range of impact velocities of 777–797 m/s. The experimental data are compared with the numerical simulation of interaction between an impactor and a multilayer transparent target.
摘要 开发了一种实验方法，可以直观地观察透明装甲每一层中损伤的开始和扩展。分析了由四层（480乘以480）-mm层和八层（300乘以300）-mm层组成的多层装甲的损伤发展动态。在总质量为 59.2 g 的 12.7 毫米双组分弹芯子弹和总质量为 10.9 g 的 7.62 毫米双组分弹芯子弹沿法线和锐角的影响下，在 777-797 m/s 的撞击速度范围内，获得了损伤的演变过程。实验数据与撞击器与多层透明目标之间相互作用的数值模拟进行了比较。
