The construction industry faces a growing demand for sustainable and resilient materials. Laminated glass offers a promising solution, but its impact resistance requires further investigation. This paper presents a development of a finite element (FE) model to predict the response of laminated glass panels to hard body impacts. The primary objective is to simulate the impact response of laminated glass panels using explicit FE analysis. This includes a critical examination of existing literature on FE simulations of laminated glass under various loading conditions and the implementation of the Johnson-Holmquist (JH-2) model for accurately predicting the laminated glass response under impacts. The results of the FE analysis for mid-span deflection and maximum strain compared well with those of the experimental test results. The developed FE model allows the prediction of deflection, stress, and strain in laminated glass panels subjected to impact loads. This approach paves the way for the further development of reliable FE models for impact simulations.

摘要

The construction industry faces a growing demand for sustainable and resilient materials. Laminated glass offers a promising solution, but its impact resistance requires further investigation. This paper presents a development of a finite element (FE) model to predict the response of laminated glass panels to hard body impacts. The primary objective is to simulate the impact response of laminated glass panels using explicit FE analysis. This includes a critical examination of existing literature on FE simulations of laminated glass under various loading conditions and the implementation of the Johnson-Holmquist (JH-2) model for accurately predicting the laminated glass response under impacts. The results of the FE analysis for mid-span deflection and maximum strain compared well with those of the experimental test results. The developed FE model allows the prediction of deflection, stress, and strain in laminated glass panels subjected to impact loads. This approach paves the way for the further development of reliable FE models for impact simulations.
