Assumed modes method was employed to validate the theoretical result and analyze the approximately critical bifurcation value and the post-buckling equilibria.
采用假设模态法验证了理论分析结果并得到了分岔临界值和近似后屈曲解。

Allowed the local buckling of elements and made use of the post-buckling strength, the effective width method is often used to calculate the load-carrying capacity.
为了用料经济，允许板件产生局部失稳，其承载能力以利用板的屈曲后强度为特点的“有效宽度”方法来计算。

Based on the classical nonlinear plate theory, axisymmetric post-buckling behavior of a functionally graded circular plate under radial compression was investigated.
