buckling modal的用法和样例：
例句
- In the symplectic method, the axisymmetric and non-axisymmetric buckling modes can be obtained directly.
这种辛方法克服了传统振型函数方法的局限性，并可直接得到轴对称和非轴对称的屈曲模态。 - Experiment results also reveal that stiffened thin-walled composite plate can bear greater load after buckling.And buckling mode change after stringer adhesive fails.
试验还发现复合材料薄壁加筋板结构有较高的后屈曲承载能力，后屈曲过程中由于桁条脱胶会造成屈曲模态的变化。
