本文将文献[1]、[2]、[3]中基于层合理论和八节点实体单元发展起来的层合/实体单元法（LW/SE）推广到多层夹芯复合材料夹层结构的静力响应和自由振动分析。在LW/SE方法中，层合板采用分层理论模拟，芯层采用八节点实体单元离散。利用位移协调条件和内力平衡条件，建立了复合材料夹层板的总控制方程。在数值算例中，对具有双层蜂窝和金字塔形网格芯层的复合材料夹层板进行了静力分析和自由振动分析。利用MSC.Patran/Nastran程序开发的三维弹性模型对所提出的方法进行了验证。针对双层蜂窝夹层板的局部响应问题，提出了两种局部模型，在保证局部响应分析精度的前提下，减少了计算量。
The Layerwise/Solid-Element (LW/SE) method, which was developed based on the layerwise theory and the eight-noded solid element for the laminated composite stiffened plates and sandwich plates in the previous works [1], [2], [3], is extended to the static response and free vibration analysis of the composite sandwich structures with multi-layer cores. In the LW/SE method, the layerwise theory is used to model the behavior of the laminated composite facesheets while the eight-noded solid element is employed to discretize the cores. The total governing equations of the composite sandwich plates are assembled by using the compatibility conditions to ensure the compatibility of displacements and the equilibrium conditions to ensure the equilibrium of internal force at the interface between facesheets and cores. In the numerical examples, the static analysis and free vibration analysis of the composite sandwich plates are investigated for the sandwich plates with double-layer honeycombs and pyramidal lattice cores. The proposed method is validated by using the 3D elastic models developed in MSC.Patran/Nastran code. Two kinds of local models of the sandwich plates with double-layer honeycombs are presented for the local response problems to reduce the computational cost in the case of guarantee analysis accuracy of the local response.
