摘要
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。借助正则摄动方法,给出了杆的极限荷载对杆的缺陷幅度依赖关系的渐近表示。本文同时也指出了[1]中(1.17)、(1.18)、(1.19)的错误并给以纠正。
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. By means of the regular perturbation, this paper gives the limit load as a function of the imperfection amplitude and its asmptotical expression. In the investigation, the author discovers mistakes of (1.17), (1.18), (1.19)in the literature and gives corrections.
