3.1.10.82. BeamEndContact3D Element

This command constructs a three-dimensional contact element between a beam end (nodes i-j) and a secondary node using a Lagrange multiplier node. Use with -ndm 3.

element BeamEndContact3D $eleTag $iNode $jNode $secondaryNode $lambdaNode $radius $gapTol $forceTol <$cFlag>

Argument	Type	Description
$eleTag	integer	unique element tag
$iNode $jNode	integer	beam end nodes
$secondaryNode	integer	secondary (contact) node
$lambdaNode	integer	Lagrange multiplier node
$radius	float	beam radius used in contact geometry
$gapTol	float	gap tolerance for contact detection
$forceTol	float	force tolerance for contact equilibrium
$cFlag	integer	optional initial contact flag

Note

A penalty variant is available as BeamEndContact3Dp.

Example

1. Tcl Code

element BeamEndContact3D 1 1 2 10 11 0.25 1.0e-6 1.0e-6

2. Python Code

element('BeamEndContact3D', 1, 1, 2, 10, 11, 0.25, 1.0e-6, 1.0e-6)
