To penetrate armor, a projectile's point concentrates force in a small area, creating a stress large enough that the armor fails. a species of jellyfish launches a pointed needle that can penetrate the hard shell of a crustacean. the rapid deceleration on impact creates a 32 μn force on the tip, which has a very small 15 nm radius. how does this compare to the ultimate stress of steel?
