| 摘 要： | 本文提出由多个正交各向异性层粘合而成的扁平双曲壳体的一种分析方法.文中以层间位移分量作为基本未知函数,并将层间应力平衡条件在建立基本平衡方程式之前,先行引进.此外:在计算各单层横向剪切变形影响时,采用单层中面法线变形后维持直线,但放弃层中面法线及其正交线之间变形后保持直角的假定.算题实践说明应用本文方法,计算方便,精度高.

| Abstract: | The doubly curved orthotropic laminated shell is considered in this paper,The shell may be composed of an arbitary number of bounded layers,each of which may posses different thickness and elastic properties.In this theory the displacements between layers are considered as fundamental unknown functions.The transverse shear deformation extensional strain in earch lamina is included.Equations of equlibrium for laminae are first derived.The continuity of displacement and stress has been prescribed at the interfaces between laminae before the final governing equations are derived. |
