elastic imperfection

基本解释

In order to study how the static preloading affects on the buckling stability of columns or cylindrical shells, a simple imperfection-sensitive elastic-plastic model is used.
为了研究静力预加载荷对诸如柱、圆柱壳等结构动态稳定性的影响，采用了一种简单的缺陷敏感弹塑性模型。
In this paper, the "shooting procedure" of two-point boundary value problems is used to investigate the buckling imperfection sensitivity of columns on nonlinear elastic foundations.
本文应用两点边值问题的打靶法来研究非线性弹性地基上杆的屈曲缺陷敏感度。
The effect of initial imperfection and elastic-plastic behavior on the buckling load is considered in the FEM analysis, and the curve of load-deflection in the post buckling stage is obtained.
分析中考虑了初挠度和弹塑性对耐压壳体失稳压力的影响，得到了后屈曲阶段的载荷─挠度曲线。
