[QUOTE="CaneBrake, post: 2948383, member: 127859"] Basically the energy of the solid, more fine tip is focused on a smaller surface area. All that energy transferred to such a small surface area surpasses the strength of the material and the bullet begins to penetrate. Heat is a byproduct of that transfer of energy from pressure, friction, etc. The poly tip isn't strong enough to withstand the force of impact and yields much faster than the plate. The bullet continues to yield and deform until the poly tip completely collapses and the copper makes contact with the plate, but by then the bullet has already lost a lot of energy and the surface area of the bullet tip is much larger. Then larger tip now spreads its remaining energy across the much larger surface area and isn't enough to shear the plate. The plate yields, but it doesn't shear. [/QUOTE]
