4.2.7.8. Bbar Plane Strain Quadrilateral Element¶
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, *eleNodes, thick, matTag) eleTag
(int)unique element object tag eleNodes
(list (int))a list of four element nodes in counter-clockwise order thick
(float)element thickness matTag
(int)tag of nDMaterial
Note
- PlainStrain only.
- 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.
