The influence of metal cover plates on ballistic performance of silicon carbide subjected to large-scale tungsten projectile

The influence of metal cover plates on ballistic performance of silicon carbide subjected to large-scale tungsten projectile

Confined silicon carbide (SiC) plates covered with aluminium alloy, mild steel, and copper alloy materials of different elastic impedances were subjected to normal impact by blunt tungsten-heavy-alloy projectile of 16 mm diameter and 40 mm length, at a nominal striking velocity of 1.25 km/s. Failure...
