OG exemplary drawing
 
1. A glass substrate comprising:
a first position, wherein a tensile stress of the glass substrate is insufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate; and
a second position, wherein the glass substrate is bent relative to the first position, and wherein the tensile stress of the glass substrate is sufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate.
 
10. A product comprising:
a glass substrate having a first position, wherein a tensile energy of the glass substrate is insufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate; and
a component that bends and maintains the glass substrate in a second position, wherein the tensile energy of the glass substrate is sufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate.
