This command is used to construct a four-node quadrilateral element, which uses a bilinear isoparametric formulation with enhanced strain modes.
element enhancedQuad $eleTag $iNode $jNode $kNode $lNode type $matTag
$eleTag |
unique element object tag |
$iNode $jNode $kNode $lNode |
four nodes defining element boundaries, input in counter-clockwise order around the element. |
type |
string representing material behavior. Valid options depend on the NDMaterial object and its available material formulations. The type parameter can be either "PlaneStrain" or "PlaneStress." |
$matTag |
tag associated with previously-defined NDMaterial object |
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 zero-length element when creating an ElementRecorder object are 'force,' 'stiffness,' and 'material matArg1 matArg2 ...'
