Abstract- Laminated glass (LG) is used as windshields in automotive industry. They are also widely spread in buildings as architectural glazing. LG consists of two or more layers of glass plies adhered by an interlayer. Two soda-lime glass plies are separated by an adhesive polymer that prevents the glass plies from shattering. In this paper presents the results of experiments of three point bending test with structural laminated glass plate. For experiments laminated glass with three different interlayer thickness and two different types of interlayer material polyvinyl butyral (PVB) and ethylene vinyl acetate (EVA) are used. INTRODUCTION- Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if…show more content…
al. [7] experimentally studied the mechanical performance of the PVB laminated glass under quasi-static and dynamic loading. Outcomes show that the PVB laminated glass is a very strong rate dependent substance having nonlinearity in its constitutive performance under both dynamic loading and quasi-static conditions. Timmel et. al. [8] developed a finite element model for impact simulation with the laminated glass. Two different methodologies are used to model the laminated glass: a smeared model and a physical model, this statistically robust model is able to simulate qualitatively genuine fracture performance of the laminated glass and leads to good settlements with investigational results in a roof crush simulation
