摘要
本文分析了在均布载荷作用下边缘简单铰链支承的扁圆锥壳的轴对称屈曲问题。利用摄动法求得了临界载荷的近似解析表达式,并将结果绘成相应的曲线,可供工程应用参考。
A theoretical analysis is presented for the snap-buckling behaviour of thin shallow conical shells subject to uniform pressure wading.The approximate formulas for critical load are obtained by perturbation technique.The results are presented graphically and can be used in engineering design.
