摘要
本文在考虑材料非线性和几何非线性的情况下,分析建立了受轴向均布载荷压杆的欧拉驻值条件,用摄动法摄动求解非齐次Bessel方程,得出了问题的近似解,并着重对松木柱的后屈曲特性作了探讨。
The uniformly distributed loads along axis of the column is investigated under the past-buck- ing behavior of column with geometric nonlinear and physical nonlinear condition. The perturbation method is used to solve the Bessel equation numerical solution especially the post-bucking behavior of the redwood column.
