具有初始几何缺陷壳体几何非线性问题的基本方程

Basic equations for geometrically non-linear problems of shells with inital geometric imperfections

考虑了任意理想曲面壳体制造偏差的影响，导出了非线性几何方程与平衡方程。该方程与适当的本构方程相结合，可用于求解有初始几何缺陷壳体的几何非线性或几何与物理非线性问题。

Considered the influence of manufacturing error and derived the non-linear geometric equation and equilibrium equation for arbitrary ideal carved surface shells. They could solve the geometrynon-linear and geometric & physical non-linear problems when the equations combine with corresponding. physical equations.
