| 摘 要： | 利用有限元法分析大开孔加强的圆柱壳在外压作用下的屈曲性能,采用非线性有限元法对结构进行弹塑性分析,通过结构上最大塑性变形点的载荷位移曲线,用两倍弹性斜率法确定其极限载荷值,根据数值计算结果提出大开孔圆柱壳的稳定性设计建议.

| Abstract: | The buckling behavior of the reinforcement structure of the cylindrical shell with large opening under external pressure was analyzed by the finite element method.In terms of the load-displacement response curve computed with geometrically nonlinear FE analysis at the point of the maximum displacement in the structure,the twice-elastic-slope method was adopted to determine the ultimate load.Some suggestions for the design of cylindrical shell with large opening were set forth according to the numerical resu... |
