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, the finite element buckling model proposed in [6] is applied to elastic-plastic buckling of thin-wall reinforced semi-rigid shell structures, and the actual structure is performed using the elastic-plastic buckling analysis program DDJTJQ~[1] of thin-walled composite structures. Calculations. The calculated results are in good agreement with the measured results.
