On the problems of sandwich shells having the form of a surface of revolution and face layers of non-equal thicknesses

Fundamental equations which govern the behavior of an elasticsandwich shell having the form of a surface of revolution andface layers of non-equal thicknesses are derived,with the so-lution of Refs.[3]and[4]as special examples.The problems of the shell under the action of symmetricalloads are reduced to the solution of a displacement-function4～,where4αsatisfies a differential equation of sixth order.     

具有不等厚表层的夹层旋转壳问题

本文探讨了具有各向同性夹心及不等厚表层组成的三层旋转壳的小挠度问题,采用广义变分法,在考虑表层抗弯刚度的情况下,导出了基本方程,其特例即为文献[3],[4]的结果. 根据所导出的基本方程,本文求解对称加载的夹层旋转壳问题,将其归结为只含一个广义位移的六阶微分方程. 本文的理论可应用于复合装甲及其它工程设计.
