| 摘 要： | 应用合成展开法及正则摄动法研究了轴对称壳体的有限变形问题。合成法的优越性之一是可将各函数的量级明确表达出来，而不必根据具体边界条件和载况对它们进行量级分析。解题中引进的两个摄动参数δ和ε分别反映了壳体有限变形时的非线性性质和其具有边界层的性质．给出了几个算例及其和有限元法计算结果的比较，情况是令人满意的．

| Abstract: | In this paper, the composite expansion method (CEM) and regular perturbation method are applied to the solution of axisymmetrical shells with finite deformation. One of the advantages of CEM is that the deduced equations can be directly solved without analysing the functions, order against . Two perturbation parameters, and 6 which represent the boundary effects and the nonlinear behavior of finite deformation respectively, are used in the solution procedure. Several numerical examples are presented and compared with those obtained by finite element method satisfactorily. |
