Brick

This command is used to construct an eight-node brick, which uses the standard isoparametric formulation.

PythonTcl

Model.element("Brick", tag, nodes, material, *args, **kwargs)

Parameters:

• tag – integer tag identifying the element

• nodes – tuple of integer tags identifying the nodes that form the element

• material – integer tag identifying the nDMaterial

• args – optional arguments

• kwargs – optional keyword arguments

Note

This element can only be defined in a Model with ndm=3 and ndf=3.

Recorders

The valid queries to a Brick element when creating an ElementRecorder are

1. 'forces',

2. 'stresses,',

3. 'strains' and

4. 'material $mat args...' Where $mat refers to the material object at the integration point corresponding to the node numbers in the isoparametric domain.

Example

The following example constructs a brick element with tag 1 between nodes 1, 2, 3, 4, 5, 6, 7, 8 with an nDMaterial of tag 1 and body forces given by varaiables b1, b2, b3.

1. Python Code

   model.element("Brick",1, (1,2,3,4,5,6,7,8), 1, (b1, b2, b3))
   

2. Tcl Code

   element Brick 1 1 2 3 4 5 6 7 8 1 $b1 $b2 $b3
