弹体侵彻YAG透明陶瓷/玻璃的剩余深度

为了研究钇铝石榴石(yttrium aluminum garnet, YAG)透明陶瓷及玻璃材料的抗弹性能和冲击破坏机制，开展了12.7 mm穿甲燃烧弹侵彻YAG透明陶瓷/玻璃的剩余侵彻深度实验研究。基于变形侵彻和刚性侵彻机制建立理论模型分析子弹撞击YAG透明陶瓷和玻璃的作用过程，并利用空腔膨胀模型确定了剩余弹体对2024T351航空铝的剩余侵彻深度。实验结果表明:YAG透明陶瓷对子弹有较强的破碎作用，其防护能力显著高于玻璃材料。理论模型计算得到的剩余弹体质量和侵彻深度结果与实验结果吻合较好，可见本文建立的理论模型可用于评估不同面板材料的抗弹性能。

Residual penetration depth of a projectile into YAG transparent ceramic/glass

In order to study the projectile-proof performance and impact damage mechanism of yttrium aluminum garnet (YAG) transparent ceramic and glass, the residual penetration depths of 12.7 mm armor-piercing projectiles penetrating into YAG transparent ceramic/glass were experimentally studied. A theoretical model was established based on the mechanism of deformation penetration and rigid penetration to analyze the processes of the projectiles impacting the YAG transparent ceramic and glass, and the cavity penetration model was used to determine the residual penetration depth of the projectile into the 2024T351 aluminum. The experimental results show that the YAG transparent ceramic has a strong crushing effect on projectiles, and its projectile-proof ability is significantly better than that of the silicate glass. The mass of the residual projectile and the penetration depth calculated by the theoretical model agree well with the experimental results. So the established model can be used to evaluate the projectile-proof performances of different panel materials.
