摘要
圆柱壳结构受外压作用的稳定性分析采用半解析有限元法 ,即周向采用离散柱壳有限条元法 .该法具有精度高、计算结果合理等优点 .通过算例分析 。
The analysis of the buckling due to losing stability of cylindrical shells under external pressure adopts the semi analysis finite element method,which uses discrete finite element for cylindrical shells in the circumferential direction.This method has many advantages,such as reasonable result calculated,and improved the accuracy.Through the analysis of examples,that the value of adopting this method for usage to expand is extensive in engineering is pointed out.
