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.
爲了研究靜力預加載荷對諸如柱、圓柱殼等結搆動態穩定性的影響，採用了一種簡單的缺陷敏感彈塑性模型。
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.
本文應用兩點邊值問題的打靶法來研究非線性彈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.
分析中考慮了初撓度和彈塑性對耐壓殼躰失穩壓力的影響，得到了後屈曲堦段的載荷─撓度曲線。
