Numerical Analysis of Wind-Borne Debris Impact on Laminated Glass Panels
摘要
Glass is a frequently used material in modern structures. Residents in such buildings are at a high risk due to glass damage and glass fragments caused by debris impacts. This study presents a comprehensive numerical analysis of the impact behavior of laminated glass panels subjected to debris impact scenarios using LS-DYNA®. Laminated glass, consisting of multiple layers bonded together with interlayer films, is widely employed in various applications, such as automotive windshields, architectural facades, and safety glass. This study focuses on understanding the dynamic response of laminated glass panels exposed to debris impact. The model incorporates material properties, layer configurations, and impact conditions to accurately represent real-world scenarios. In this study, different sizes of steel balls are impacted on the laminated glass panels at different locations. Various impact parameters, including debris size, velocity, and location of impact, are systematically investigated to assess their influence on the performance of laminated glass. The simulation results provide insights into the deformation patterns and crack propagation during debris impact events.
