Effect of delamination size, location and boundary conditions on the behavior of a laminated glass plate

Laminated glass is made by combining glass layers with polyvinyl butyral (PVB) or a different adhesive with the help of heat and pressure. Its popularity is increasing in the building industry as a protective material. However, despite the popularity of laminated glass as a structural material, delamination is recognized as a highly undesirable problem inducing major damage to laminated glass. The effect of boundary conditions on the delamination strength of laminated glass is observed in this study. It is concluded that the location and size of delamination have a considerable effect in determining the delamination strength of laminated glass. The results of the previously conducted experiment and the developed finite element model are utilized to validate the model used to determine the delaminated strength of laminated glass. The simulation results and measurements are in good agreement with the results of the mathematical model. The results of the current research can be utilized by design engineers while designing laminated glass for structural applications.
