What happens to laminated safety glass due to induced damage in a collision?

Laminated safety glass is designed with layers that include a plastic interlayer sandwiched between two pieces of glass. When this type of glass experiences induced damage during a collision, it can indeed develop a checkerboard pattern. This pattern occurs because the impact can create a series of fractures that radiate through the glass, but the interlayer holds the pieces together, allowing for some structural integrity to be maintained. The interconnected fractures resemble a checkerboard, indicating that while the glass is damaged, it does not shatter in the traditional sense. This feature enhances safety by preventing sharp shards from becoming projectiles and helps to keep the glass intact within its frame despite damage.

In summary, the unique construction of laminated safety glass allows it to sustain damage in a manner that results in a distinct pattern, providing both a visual cue of impact and the safety benefits associated with its design.
