摘要

The aim of the work is to investigate the behavior of laminated glass plates subjected to ball drop impact. Laminated glasses are known for their safety and impact resistance. One of the important features of laminates is a sufficiently thin polymer interlayer with a pliable structure. This study evaluates the mechanical properties of a laminated glass plate configuration consisting of two glass layers and one layer of polymeric interlayer. The finite element method was used to perform the computational model, that focuses on the dependencies of displacements and first principal stresses on transverse shear strain and the interlayer plate thickness. Results indicate significant insights into the deformation characteristics and stress distribution within the laminated glass structure. The study’s outcomes provide a foundation for further research and development, particularly in optimizing the interlayer properties and thickness for better impact resistance. This work contributes to advancing the knowledge in the field of laminated glass structures, promoting the development of more resilient and safer glass products for various applications.
