夹层玻璃梁和板广泛应用于玻璃和光伏应用。这些结构的一个特征是用于嵌入太阳能电池的相对较薄且柔顺的聚合物层。光伏玻璃组件的合理设计需要对聚合物封装剂的横向剪切应变分布进行分析。本文采用一种带有玻璃表皮和聚合物芯的三层梁作为模型结构，对其力学性能进行了评价。导出了夹层玻璃梁试样三点弯曲试验中最大挠度、核心层横向剪切应变与施加力之间的鲁棒关系。采用了一阶剪切变形梁理论和分层型梁理论。给出了夹层玻璃梁横向剪切刚度的表达式。最大挠度的计算结果与文献中讨论的结果进行了比较。此外，还进行了三维有限元分析，以验证所应用的梁理论。对不同聚合物材料夹层玻璃梁进行了三点弯曲试验。对最大挠度的实验数据与推导式进行了比较。
Laminated glass beams and plates are widely used in glazing and photovoltaic applications. One feature of these structures is a relatively thin and compliant polymeric layer for embedding solar cells. Proper design of photovoltaic glass modules requires an analysis of transverse shear strain distribution in polymeric encapsulant. In this paper a three layered beam with glass skins and a polymeric core is applied as a model structure to evaluate the mechanical properties. Robust relationships between the maximum deflection, the transverse shear strain of the core layer and the applied force in a three-point-bending test of laminated glass beam samples are derived. The first order shear deformation beam theory and a layer-wise type beam theory are applied. An expression for the transverse shear stiffness of the laminated glass beam is presented. The results for the maximum deflection are compared with the results discussed in the literature. Furthermore, a three-dimensional finite element analysis is performed to verify the applied beam theories. Three-point-bending tests for laminated glass beams with core layers from different polymeric materials are performed. The experimental data for the maximum deflection are compared with the derived expressions.
