摘　　要：采用逐段光滑位移矢假设，考虑了横向剪应力在层间的连续及表面的协调，用最小位能原理建立了复合材料面层夹层析的精化理论，所得控制方程含有７个未知量。本文理论可视为Ｌｉｂｒｅｓｃｕ夹层板模型的精化形式，它可直接计算出数值甚小但工程上颇为重要的层间应力。By using the principle of staionary potential energy, a refined theory for sandwich plates faced with laminated composites is established on the assumption of layer-wise smooth displacement vector. which accounts for continuous or compatible conditions of transverse shear stresses at interfaces and on boundary surfaces. The governing equations include seven unknown functions. The theory can be treated as the refined form of the Librescu's model. The transverse shear stresses at interfaces which are smaller but rather important in engineering can be calculated from this theory.
