在分析夹层板芯、皮材料差异较大的情况下，应采用LayerWise公式，本文采用径向基函数配点法和一种新的各层独立转动、厚度拉伸的LayerWise理论，对夹层板进行了静力和自由振动分析。在此基础上，精确计算了层合板和夹层板的横向法向和剪切变形和应力，并通过统一的形式自动实现了运动方程的求解和径向基函数插值，最后对复合材料层合板和夹层板的算例进行了测试和讨论。
In the analysis of sandwich laminates, where core and skin materials are so different, layerwise formulations should be adopted.In this paper the static and free vibration analysis of sandwich plates by the use of collocation with radial basis functions and using a new layerwise theory with independent rotations in each layer and thickness stretching was performed. With this formulation, transverse normal and shear deformations and stresses are accurately computed.The equations of motion were automatically implemented via a Unified Formulation and interpolated with radial basis functions.Finally composite laminated plate and sandwich plate examples were tested and discussed.
