Eigenvalue BucklingThe Eigenvalue Buckling system predicts the theoretical buckling strength of an ideal elastic structure. This method corresponds to the textbook approach of elastic buckling analysis; for instance, an Eigenvalue Buckling analysis of a column matches the classical Euler solution. However, imperfections and nonlinearities prevent most real-world structures from achieving their theoretical elastic buckling strength. The Eignevalue Buckling analysis often yields quick but non-conservative results.An Eigenvalue Buckling analysis must follow a prestressed static structural analysis. Follow the instructions in Static Structural to build a prestressed Static Structural system, and then complete the following instructions to build and link an Eigenvalue Buckling system.

特征值屈曲特征值屈曲系统预测了理想弹性结构的理论屈曲强度。这种方法相当于教科书上的弹性屈曲分析方法；例如，对一个柱子的特征值屈曲分析与经典的欧拉解决方案相匹配。然而，不完善和非线性因素使大多数现实世界的结构无法实现其理论上的弹性屈曲强度。Eignevalue Buckling分析通常会产生快速但不保守的结果。特征值屈曲分析必须在预应力静态结构分析之后进行。按照静态结构中的说明建立一个预应力静态结构系统，然后完成以下说明来建立和连接一个特征值屈曲系统。
