摘要
本文将文[6]提出的有限元屈曲计算模型推广运用于薄壁加筋半硬壳结构的弹塑性屈曲情况,利用薄壁组合结构弹塑性屈曲分析程序DDJTJQ~[1]对实际结构进行了计算。计算结果与实测结果较好吻合。
In this paper, a finite element model for elasto-plastic buckling analysis of the 'semirigid shell structures under axial compression is presented according to the stress behavior and the experimental buckling phenomena. The application to three practical engineering structures shows that the numerical results using the code DDJTJQ-4 with the finite element model developed here are in better agreement with its experimental values.
