The concentric circle cracks will be on the force side. This means, the circular cracks will be on the side of the glass which the bullet came from.
The Scientific name for Bullet Proof Glass is Bullet Resistant Glass. It is referred to as Bullet Resistant Glass in the Industry as there is no such glass that can stop every bullet. A series of bullets that hit within a small area of the Bullet Resistant Glass will eventually project right through the glass.
an original glass to bullet resistant glass
Bulletproof glass is made by sandwiching multiple layers of materials, such as glass and polycarbonate, together. This combination of materials is designed to absorb and dissipate the energy from a bullet, preventing it from penetrating through the entire thickness of the glass. The specific construction of the glass allows it to deform and absorb the impact of the bullet, stopping it from passing through.
No airplanes do not have bullet proof glass.
is wider on the exit side due to the impact and force of the bullet. This is because the glass fractures and breaks away as the bullet passes through, resulting in a larger hole on the side where the glass breaks.
No it cant go through it.
Glass is usually made shatter proof in order too prevent long sharp pieces of glass injuring people. This is done by either applying a clear sheet of plastic too the glass, or the glass sheet is heated till just below the softening point and then cold air is blasted onto the glass, this way when the glass breaks into small chunks which would explain why in some cases the bullet only punctured a hole instead of shattering the whole sheet of glass.
It depends on the thickness of the glass and the muzzle energy of the bullet, not just the velocity.
For one, the US President uses bullet proof glass.

Direction of spin is dependent on the direction of the rifling on the inside bore of the barrel. A bullet will spin the same direction as the rifling.
you need 2 layers of laminate and liquid glass, so the bullet punctures on layer but not the other
