This command is used to construct a ShellMITC4 element object, which uses a bilinear isoparametric formulation in combination with a modified shear interpolation to improve thin-plate bending performance.
element ShellMITC4 $eleTag $iNode $jNode $kNode $lNode $secTag
$eleTag |
unique element object tag |
$iNode $jNode $kNode $lNode |
four nodes defining element boundaries, input in counter-clockwise order around the element. |
$secTag |
tag associated with previously-defined SectionForceDeformation object. Typically, corresponds to some PlateFiberSection, elastic or otherwise |
Should the element be required to compute a mass matrix, a consistent translational element mass matrix is computed. Rotational-inertia terms are ignored.
The valid queries to a shell element when creating an ElementRecorder object are 'force,' 'stiffness,' and 'material matArg1 matArg2 ...'
