Finite Element Analysis of Laminated Glass Plates Subjected to Impact Loading

Laminated glass is a type of glass formed by placing an intermediate layer, called PVB (polyvinyl butyral), between two or more glass plates. The joining of the layers takes place with the aid of heat and pressure. As a result of the processes carried out, the adhesion of the PVB appears and the layers appear as a single glass. Due to this feature of the intermediate layer, even if the glass breaks in the face of earthquake, storm, impact and similar events, it does not scatter around. As a result of the fracture, a spider web-like appearance is formed. Nevertheless, it is the least damaging of consequences such as the damage of living things. Laminated glass was first used in the automotive industry in 1914. Recently, there has been a noticeable increase in the use of many areas, especially in construction industry. The purpose of this work is to analyze effect of impact loads on mechanical behavior of laminated glass plates using finite element method. Laminated glass plate is analyzed as fixed supported. Results are presented in figures. As result of study, it is observed that geometry of impactor and the interlayer material are the factors that effect impact behavior of laminated glass unit.
