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 $thick $type $matTag |
| $eleTag | unique element object tag |
| $iNode $jNode $kNode $lNode | four nodes defining element boundaries, input in counter-clockwise order around the element. |
| $thick | element thickness |
| $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 of nDMaterial |
NOTE:
- The valid queries to a Quad element when creating an ElementRecorder object are 'forces', 'stresses,' and 'material $matNum matArg1 matArg2 ...' Where $matNum refers to the material object at the integration point corresponding to the node numbers in the isoparametric domain.
