目前的贡献涉及异质光伏模块核心层机械性能的计算均质化。这是必需的，因为用于有效全局结构分析的新颖分层理论的机械方法基于均质层。这种分层理论建立在板的直接方法的基础上，其中所有考虑因素都仅限于单个层的可变形中表面。由于芯层的几何结构，导致有效替代材料的各向异性材料行为。由此产生的机械性能的方向依赖性被指定并可视化。最后，基于上述工作，将三维柯西连续体获得的各向异性弹性结果转化为表面弹性的刚度度量。 (C) 2016 Elsevier Ltd. 保留所有权利。
The present contribution is concerned with the computational homogenisation of mechanical properties of the heterogeneous photovoltaic module core layer. This is required since the mechanical approach with a novel layerwise theory used for efficient global structural analysis is based on homogeneous layers. This layerwise theory is build on the direct approach for plates, where all considerations are restricted to the deformable midsurface of the individual layer. Due to the geometric structure of the core layer, an anistropic material behavior of the effective substitute material results. The resulting orientation dependence of mechanical properties is specified and visualized. Finally, based on aforementioned work, the results of anisotropic elasticity gained for the three dimensional Cauchy continuum, are transferred to stiffness measures of surface elasticity.
