Abstract :

Laminated glass is a kind of safety glass which consists of two glass layers with an interlayer Polyvinyl Butyral (PVB) in between them. Even if the breaking happens, the glass layers are held together by the PVB interlayer and minimize the risk of injury. Laminated glass units have long been used in the transportation and automotive industries. Because of their resistance to a wide range of loading and environmental condition, nowadays they are extensively used in architectural glazing products Laminated glasses display highly complicated structural behavior because they can easily perform large displacement since they are very thin and there is a big difference between the material properties. Because of mathematical complexity and discontinuous stress distributions of laminated glass units most of the studies are about linear behavior rather than nonlinear behavior of the laminated glass units. In the current study, a finite element model is developed for the analysis of cylindrical laminated glass shells and experimental studies are carried out for the validation of model. It is observed from the figures presented, numerical results and experimental results from the tests are in good agreement.
