| Abstract |
This study investigates the minimum force required to break residential windows when struck by wooden projectiles. Using an air cannon, the
speed of the projectiles was controlled by adjusting the air pressure. Six different projectiles with varying weights and velocities were tested
on tempered glass to analyze the impact. The results showed that the momentum needed to break the glass was lower than previously
reported values. Specifically, the 8mm tempered glass broke at a momentum of around 10.50 kg·m/s, while the 12mm glass shattered at
approximately 13.5 kg·m/s. These findings were compared with finite element analysis to identify trends in glass breakage. The simulation
also recommended that 16mm thick glass would be ideal for resisting type B impacts. |
