组合壳屈曲和后屈曲分析

Buckling and postbuckling analysis of shell assemblies

讨论组合壳屈曲和后屈曲分析中有关两壳交线上节点广义位移的转换矩阵和刚度矩阵修改等问题，给出具体的转换矩阵．并用它分析计算了断面为L型，Z型和H型三种壳体结构．

The buckling and postbuckling behaviour of shell assemblies are studied,in which the conversion of the generalized displacement of nodes on intersection line of two shells and modification of stiffness maxtrixes are discussed. The concrete conversion matrixes are shown in this paper. The shell assemblies with L,Z,H section are analysized and computed and good results are abtained.
