多夹层板壳的非线性理论及应用(Ⅱ)──正交异性材料扁壳的基本方程
Nonlinear Theory of Multilayer Sandwich Shells and Its Application (Ⅱ)-Fundamental Equations for Orthotropic Shallow Shells
-
摘要: 本文把文[1]建立的多夹层壳体的中小转动一阶大挠度理论,具体地运用到多夹层扁壳中去给出了正交异性材料的多夹层扁壳的大挠度问题平衡方程和边界条件及其特例,宏观各向同性材料多夹层扁壳的大挠度方程.Abstract: This paper applied the simplified theory for multilayer sandwich shells undergoing moderate/small rotations in Ref. [1] to shallow shells. The equilibrium equations and boundary conditions of large deflction of orthotropic and the special case, isotropicshells, are presented.
