特征值

Eigenvalue buckling analysis can only forecast the theoretical buckling strength of an ideal linear elastic structure, because of the unideal property of material and geometrical nonlinearity, most structures can not reach their theoretical strength limit.

特征值屈曲分析只可预测一个理想线弹性结构的理论屈曲强度，材料非理想性与几何非线性使得大多数结构无法达到它们理论强度极值。

Accordingly, fuzzy sets method is introduced to process the fuzzy information of the parts' appearance. This method takes appearance age as its universe of discourse to describe the standard appearance feature value of the parts, and uses fuzzy numbers to describe the linguistic values that represents the severity degree of the parts' appearance.

The "compressed sparse row data format" is adopted to save storage and the "mode multiplication" is used to improve the computation efficiency, so that the finite integration equation is obtained with low storage and high efficiency. To solve the finite integration equation, which is a large-scale sparse algebraic eigenvalue problem under the condition specified, the Krylov subspace iteration method is introduced and the shift-invert Arnoldi method is proposed to exclude the unphysical static electro-magnetic solution and get the needed eigensolution around the specified eigenvalue.
