摘要: 本文推导了一个半解析加筋锥壳元(图1)的线性刚阵和几何刚阵,该元可用于加筋旋转壳在任意载荷下的弹性稳定性分析。规定环向筋条和纵向筋条分别置于壳元的母线和周线上。

Abstract: The linear and geometric stiffness matrices of a semianalytical stiffened conical shell element are derived in this paper. This element can be used for elastic buckling analysis of a stiffened shell of revolution under arbitrary loads, Two numerical examples are analyzed and the results show that this element is available.
