Strength and Deformation Behavior of Laminated Glass

Dr. Tammy Amos & Dr. Stephen J. Bennison, DuPont de Nemours & Co. Inc.

After a decade of research, a clear picture of the strength and deformation behavior of laminated glass has now been established. In this contribution we show three methods for computing the stress and deflection behavior of laminates and compare the methods to validation experiments. Key to the accurate structural analysis of laminates is adequate characterization of the time-temperature nature of polymer interlayers. Particular emphasis is placed on how to treat time and temperature effects on strength and how different types of interlayer affect the performance of the laminate. Established and emerging standards for assessing the structural performance of laminated glass are discussed in context of the progress made in this subject. Availability of software packages to aid in the strength design of laminated glass is also discussed. The approaches presented enable efficient structural design of laminates allowing full performance potential to be realized.
