3.1.10.34. ShellNLDKGQ Element

This command constructs a four-node quadrilateral shell element with geometric nonlinearity based on the updated Lagrangian formulation. It extends the ShellDKGQ Element element for large-deformation analysis. Use with -ndm 3 -ndf 6.

element ShellNLDKGQ $eleTag $iNode $jNode $kNode $lNode $secTag <-damp $dampTag>

Argument	Type	Description
$eleTag	integer	unique element tag
$iNode $jNode $kNode $lNode	integer	four nodes in clockwise or counter-clockwise order
$secTag	integer	tag of a previously defined section object
$dampTag	integer	tag of an elemental damping object used with -damp (optional)

Note

1. The section may be a PlateFiberSection, ElasticMembranePlateSection, or layered shell section.

2. Valid Element Recorder queries include forces, stresses, and material $matNum ....

Example

1. Tcl Code

section PlateFiber 1 1 10.0
element ShellNLDKGQ 1 1 2 3 4 1

2. Python Code

section('PlateFiber', 1, 1, 10.0)
element('ShellNLDKGQ', 1, 1, 2, 3, 4, 1)
