Experimental method for studying the interaction processes of high-velocity impactors with multilayer transparent armor

An experimental technique has been developed that allows one to visualize the occurrence and spread of damage in each layer of transparent armor. The dynamics of damage development in multilayer packages consisting of four and eight layers with an area of 480 $\times$ 480 mm and 300 $\times$ 300 mm, respectively, have been analyzed. The evolution of damage was obtained under the influence of a 12.7 mm caliber bullet with a two-component core with a total mass of 59.2 g and a 7.62 mm caliber bullet with a two-component core with a total mass of 10.9 g, both normal and at an acute angle in the range of impact speeds 777 $\div$ 797 m/s. The experimental data are compared with the results of numerical modeling of the interaction of the striker with a multilayer transparent barrier.
