The Analysis of Convergence of Shell Element with Rigid Body Displacements

Article Preview

Abstract:

Rigid body displacements have different form existing in shell element trial function, and there is a different opinion about its influence. It is borne out by adding rigid body displacements in isoperimetric shell element and solving numerical examples with several methods, that rigid displacement is so important for the convergence of shell element that shouldn’t be neglected.
