摘要
采用 Donnell 型扁壳理论,利用 Galerkin 法和广义平均筋条刚度法分析了在均布外压作用下碳/环氧复合材料三角形网格加筋圆锥壳体的总体稳定性,得到了临界载荷的解析表达式。数值结果表明,本文理论预示值与临界载荷的实验结果吻合较好。
In this paper,based on the Donnell-type theory for thin shell,atheoretical analysis is presented for the general stability of C/E compositetriangular grid conical shells under external pressure.The formulas for criticalexternal pressure are obtained by using Galerkin's procedure.Good agreementis shown between the theoretical prediction of critical external pressureand experimental data.
