Bbar Plane Strain Quadrilateral

This command is used to construct a four-node quadrilateral element object, which uses a bilinear isoparametric formulation along with a mixed volume/pressure B-bar assumption. This element is for plane strain problems only.

element bbarQuad $eleTag $iNode $jNode $kNode $lNode
        $thick $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

matTag

tag of nDMaterial

NOTE:

  1. PlainStrain only.
  2. 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.
