Abstract
This study assesses the deformation behavior and the stress distribution of a new kind of com-posite plate consisting of a glass pane and a high pressure laminate. The two single plates are adhesive laminar bonded with a silicone. Thereby, the composite react as a unit so for example, the stiffness is higher than of the single components. By means of simple calculation approaches, the deformation behavior and the stress distribution can be descripted. However, the interlayer is be idealized to a thin layer with a maximal high or low stiffness. First comparisons show, that there are big differences between that two approaches in the calculated deformation and stress-es. Hence in this study, additional experiments with the composite plate purpose to evaluate the quality of that nonlinear calculation. In four-point bending tests, according DIN EN 1288-3, the deformation and in six point the tensile stress is measured. The results shows, there are increas-ing differences between the calculation approaches and the measurements, when increasing the load of the plate. In Addition, it is not possible to consider nonlinear effects or higher stresses on the plate edges. Hence, simple calculation are unsuitable to describe the mechanical behavior of the new composite plate. Hence, as assessment basis for glass hybrid plates other calculation approaches are necessary. Therefor this study assesses nonlinear finite element analysis of the new composite. Assuming simple material models for the complex behavior of the hyperplastic silicones, the study shows that for application-relevant forces and deformations, the calculation can be done quickly and easily with a sufficiently low scattering.
