Abstract
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 Al2O3, B4C, and SiC 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.
