Based on this, the complex constraint method has been used to get the buckling load for the whole axisymmetric shell by solving the eigenvalue problem for only one substructure without introducing any additional approximation.

• 根据这一特点，采用复约束方法，通过求解单个子结构的屈曲方程得到了整个结构的屈曲载荷和模态，大大减小了所求解问题的规模，并且在此简化过程中没有引入任何附加的近似。
