Abstract
Laminated glass (LG) is created by bonding multiple glass layers using a polymeric interlayer, which reduces the risk of glass shards by keeping the pieces connected. The interlayer also absorbs cracking energy. This study examines the mechanical properties of three polymeric films (PVB, EVA, and SentryGlas) through tensile tests at different strain rates. The effect of glass type and thickness on the failure and deflection of LG windows is investigated using a full-scale water chamber. To address safety concerns and costs, a dynamic numerical model of LG windows is developed using ANSYS AUTODYN. The model's accuracy is validated against existing experimental data. The results show that tempered glass panels withstand higher pressure than annealed glass panels. Increasing glass thickness enhances the resistance of LG at the pre-cracked stage, with a 10% improvement for EVA and SentryGlas interlayers and a 153% increase for PVB interlayers. However, there is no significant impact on the LG at the cracked stage.
