具有玻璃表皮层和聚乙烯醇丁醛芯层的夹层板广泛应用于土木工程和汽车工业。晶体或薄膜光伏组件由正面和背面玻璃或聚合物层和嵌入在聚合物封装剂中的太阳能电池层组成。对于这类层合板的结构分析，已有文献介绍了板的分层理论。本文提出了一种扩展LWT来保证C-0的连续性。在此基础上，提出了一种具有二次形函数和九自由度的自定义四边形偶然性单元的有限元表达式。该元素是使用Abaqus子程序“User element”实现的。基准问题的开发是为了检查所提出的单元的精度和效率为广泛的材料性能，包括剪切柔性和剪切刚性层压板的极限情况。重点放在边界条件对附加自由度的影响以及边界层效应的准确表示上。(C) 2015 Elsevier Ltd.版权所有。
Laminated plates with glass skin layers and a core layer from polyvinyl butyral are widely used in the civil engineering and automotive industry. Crystalline or thin film photovoltaic modules are composed from front and back glass or polymer layers and a solar cell layer embedded in a polymeric encapsulant. For the structural analysis of such laminates, layer-wise theories (LWTs) for plates have been introduced in literature. In this paper, an extended LWT is proposed to assure the C-0 continuity. Based on this theory, a finite element formulation and a user-defined quadrilateral serendipity element with quadratic shape functions and nine degrees of freedom (DOFs) is presented. The element is implemented using the Abaqus subroutine "User Element". Benchmark problems are developed to examine the accuracy and efficiency of the proposed element for a wide range of material properties including the limiting cases of shear compliant and shear rigid laminates. An emphasis is placed on the influence of boundary conditions with respect to additional degrees of freedom as well as on accurate representation of boundary layer effects. (C) 2015 Elsevier Ltd.
