变厚度夹层板的弯曲问题

The Bending of Sandwich Plates with Core Thickness Variation

以三个广义位移和夹芯厚度为基本变量，以 Ｒｅｉｓｓｎｅｒ 理论的基本假设为基础，建立了夹芯层厚度沿一个方向线性变化的三层夹层板弯曲问题的偏微分方程当令 ＝ ０ 时。

In this paper the partial differential equations have been established for the sandwich plate with core thickness linearly varied in one direction. The basic variables in the equations are three general displacements ψ x,ψ y and w as well as the core thickness h . When the angle  is equal to zero the equations will be degenerated to the classic equations for the sandwich plates with the unvaried thickness.
