Stone fling hole II – laminated glass

Mechanic spot load – short-term – large dynamics

Type of glass	Only laminated glass. In the case of armoured glass – the similar situation
Examples	Stone or another bullet from the sling; Stone hit into the front windscreen of a car at high speed
Beginning	Fissure centre without an opening; Irregular rough edge; At the side of the fling - the conical break in the glass.
Lines of process	Irregular cone fissure with short beams from the fissure centre, not always regularly centrifugal.
End	At the side opposite to the inlet; A remarkably larger outlet opening.
Other features	Irregular fissure in the glass; Often small crosscut fragmentations; Round form = upright hit; Oval shape = diagonal hit; Large kinetic energy = ornamental cone = acute/sharp edge; Smaller kinetic energy = flat cone form = larger opening; Rear fragmentations in the opposite outlet side.
