摘要
采用“退化等参板壳元”及“板壳强度，稳定性的非线性有限元分析程序”，将波形初始缺陷对板壳的临界载荷影响作了分析讨论，得出了一些有益的结论，并提出了解决问题的方案。
This paper analyses and discusses the influence for waved original defects to the critical loans of plates and shells by the method of degenerating plates and shells element and the nonlinear finite element analysing proceed to the strength and stability of plates and shells. It gets some profitable conclusions and gives some plans to solve problems.
