摘要
给出了等参壳单元中补充刚体位移的又一方法，通过算例分析说明了刚体位移对壳单元解的收敛性影响。
Rigid body displacements have different form existing in shell element trial function, and there is different opinions about its influence. It is borne out by adding rigid body displacements in isoparametric shell element and solving numerical examples with several methods, that rigid displacement is so important for the convergence of shell element, shouldn't be neglected.
