Laminated safety glass (LSG) consists of at least two glass panes that are bonded together by a polymer interlayer. In the event of fracture, this has the advantage that the glass fragments adhere to the interlayer, allowing the laminate to retain a residual load-bearing capacity. This characteristic post-fracture behavior is influenced by numerous factors – in particular, the geometry and arrangement of the cracks play a decisive role.

The aim of the study is to investigate how key parameters of the crack structure – such as the degree of fragmentation, geometry, orientation, and configuration of the cracks – affect the residual load-bearing capacity of laminated safety glass.
