摘　　要：探讨了具有各向同性硬夹心的3层夹层板问题,在考虑各层抗弯刚度及夹心横向弹性的情况下,采用广义变分法,导出了反对称变形的4个基本方程及正对称变形的1个基本方程。Fundamental equations governing the behavior of a plate having sandwich construction are derived. Bending rigidity of the facing layers and the core as well as the transverse elasticity of the core are considered. Variational procedure is used to obtain the fundamental equations.

关 键 词：夹芯层板 硬夹心 夹心横向弹性
