| Abstract: | 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. |

| Keywords: | rigid body displacement shell element finite element |
