| 摘 要： | 基于壳体初挠曲理论,对具有环形初始几何缺陷的圆柱壳进行了静力分析。整个缺陷区段视为由若干斜锥段组成。利用广义样条子域法建立了位移模式,该模式具有自由度少,结点设置灵活之特点。计算结果与有限元计算所得结果基本吻合。

| Abstract: | Based on the theory of initial deflection of shell1], the cylindrical shells with ring shape geometrical imperfection is statically analyzed in this paper. The whole imperfection region is regarded as a combination of several skew cones. The displacement mode is established by using generalized spline subdomain methods which has the advantage of fewer degrees of freedom and arbitrarily setting nodes. The computational results is basically identical with the solutions by finite element methods. |
