非线性薄壳的一般理论

本文按照简化了的易曲物体的形变理论,并根据虚位移原理给出了薄壳的大变形变分原理。从而导出非线性变形的平衡方程和边界条件。最后对园筒受均匀外压的大变形问题进行了分析。

General Theory of Nonlinear Thin Shells

This paper gives the variasional principle of large deformation on the basis of simplified deformation theory of flexible body and in accordance with he principle of virtual displacement, Therefore the equilibrium equations and boundary conditions of honlinear deformation are derived. Finally the large deflection problem of length circular tube uniformly compiessed is disscu-ssed.
