摘要
本文采用扁壳杂交单元和浅曲梁杂交单元,分析了椭圆度、不平直度等常见初始几何缺陷对圆柱壳承载能力的影响,以及轴压与外压联合作用下的相关屈曲特性.
The hybrid shallow shell element and the shallow beam element
are employed to analyse the influence of initial ovality,out-of-straightness
deviation and other common imperfections on the safety of cylindrical shells.
The correlation characteristic buckling of the cylindrical shell with combin-
ed axial load and external pressure are also discussed.
