elastic imperfection

基本解釋

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.
為了研究靜力預(yù)加載荷對(duì)諸如柱、圓柱殼等結(jié)構(gòu)動(dòng)態(tài)穩(wěn)定性的影響，采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(yīng)用兩點(diǎn)邊值問題的打靶法來研究非線性彈性地基上桿的屈曲缺陷敏感度。
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(duì)耐壓殼體失穩(wěn)壓力的影響，得到了后屈曲階段的載荷─撓度曲線。
