This command is used to construct a ShellNLDKGQ element object accounting for the geometric nonlinearity of large deformation using the updated Lagrangian formula, which is developed based on the ShellDKGQ element.
|element ShellNLDKGQ $eleTag $iNode $jNode $kNode $lNode $secTag|
|$eleTag||unique element object tag|
|$iNode $jNode $kNode $lNode||four nodes defining element boundaries, input in clockwise or counter-clockwise order around the element.|
|$secTag||tag associated with previously-defined SectionForceDeformation object.
Currently can be a PlateFiberSection, a ElasticMembranePlateSection and a LayeredShell section.
- Three examples of this element can be found on the following URL
