| 摘 要： | 应用初始后屈曲理论研究圆柱壳在轴区及侧压同时作用时后屈曲性态及其对 非对称周期性缺陷和局部“点坑”缺陷的敏感性．得到了临界载荷因子与缺陷大小的关 系曲线。结果表明，后屈曲对于非对称周期性缺陷敏感性高于对于局部“点坑”缺陷的 敏感性。

| Abstract: | The postbuckling behavior and imperfection sensitivity of a cylindrical shell loaded axially and laterally is studied. The curve which shows the relationship between critical load factor and magnitude of imperfection is obtained. The results show that imperfection sensitivity to postbuckling is higher forimperfections of assymetric type than for those of localized type. |
