Impact resistance of ceramics in a numerical experiment

A series of computations based on experimental data on the depth of projectile penetration into targets is performed for verification of parameters of ballistic stability of plates made of $\mathrm{Al}_2\mathrm{O}_3$, $\mathrm{B}_4 \mathrm{C}$, and $\mathrm{Si}\mathrm{C}$ ceramics. Interaction of a heart-shaped steel projectile and a target made of an aluminum alloy with a variable-thickness ceramic plate positioned ahead of the target is simulated. The computed results are compared with experimental data for various ceramic targets 1–5 mm thick and projectile velocities of 810–850m/s.
