对等效单层和分层叠合板理论及其有限元模型进行了综述。介绍了作者提出的分层理论，介绍了变位移有限元模型和网格叠加技术。本文还介绍了一种基于变运动学理论和网格叠加法的同时多模型方法。同时多模型方法的目标是根据子区域的物理特征、应用负载、预期行为和所需的解精度水平，将最合适的数学模型与每个子区域相匹配。因此，在不牺牲解的准确性的情况下，解的经济性得到了最大化。
A review of equivalent–single–layer and layerwise laminated plate theories and their finite element models is presented. The layerwise theory advanced by the senior author is presented and a variable displacement finite element model and mesh superposition techniques are described. A simultaneous multiple model approach that is based on the variable kinematic theory and the mesh superposition method are also described. The objective of the simultaneous multiple model approach is to match the most appropriate mathematical model with each subregion based on the physical characteristics, applied loading, expected behavior, and level of solution accuracy desired in that subregion. Thus solution economy is maximized without sacrificing the solution accuracy.
