initial displacement imperfection的意思|示意

The stress displacement equations of cylindrical shell with initial imperfection are deduced on the basis of definitions of imperfection.

基于初始缺陷的定义式，推导出有初始缺陷的圆柱壳的几何方程。

Based on the consistent mode imperfection method, the initial defect model was determined by the least order mode of eigenvalue buckling, and the maximum displacement value.

初始缺陷的模型是根据一致缺陷模态法，按最小特征值屈曲模态分布，并控制其最大值的方法确定。
