The Effect of Glass Plate Thickness and Type and Thickness of the Bonding Interlayer on the Mechanical Behavior of Laminated Glass

摘要

In this work the effect of the type of the bonding interlayer (polyvinyl butyral (PVB) or Ethyl Vinyl Acetate (EVA)), number of bonding layers, and the position and the thickness of the Glass plates on the maximum load capacity and absorbed energy by laminated glass. Furthermore, this investigation presents a mathematical model that relates the maximum force capacity of the glass laminated structure to the glass plate thickness, type and thickness of the inter-layer regardless the position of the fixed glass plate. Both practical work results and the theoretical model indicate that the maximum load capacity of laminated glass bonded with either PVB or EVA decreases as the interlayer thickness increases. Moreover, the maximum load capacity for the glasses bonded with EVA is greater than those for the PVB bonded ones under the same conditions. On the other hand, it was observed that that laminated glass absorbed energy increases with the increase of the interlayer thickness and the increase of glass plate thickness.
