3.1.10.80. BeamContact2D Element

This command constructs a two-dimensional beam-to-surface contact element. A beam segment (nodes i-j) contacts a secondary node through a Lagrange multiplier node. Use with -ndm 2.

element BeamContact2D $eleTag $iNode $jNode $secondaryNode $lambdaNode $matTag $width $gapTol $forceTol <$cSwitch>

Argument

Type

Description

$eleTag

integer

unique element tag

$iNode $jNode

integer

beam end nodes

$secondaryNode

integer

secondary (contact) node

$lambdaNode

integer

Lagrange multiplier node

$matTag

integer

tag of a contact ND material

$width

float

beam width used in contact geometry

$gapTol

float

gap tolerance for contact detection

$forceTol

float

force tolerance for contact equilibrium

$cSwitch

integer

optional initial contact flag

Note

A penalty variant is available as BeamContact2Dp.

Example
