Abstract

Abstract

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.
