Abstract: This paper adopts Hu Hai-Chan's[l] differential equations for isotropic thick plate (sandwich plate) and corresponding boundary conditions. The unknown constants are determined by means of least square boundary method. The domain method for Galerkin is adopted to satisfy the differential equations. Computed results show high accuracy and practical simplicity.

摘要： 本文采用胡海昌中厚板(各向同性夹层板)的微分方程及边界条件,用最小二乘边界积分法确定试函数及加权残数法内部法满足微分方程,以便确定常数。计算结果表明,精度高且实用简便。
