Damper01

Viscous/Nonviscous Damper

This damper uses displacement and velocity as inputs, not strain and strain rate, which means element length is not used to compute strain or strain rate.

Damper01

This Damper01 is a simple 2D viscous/nonviscous damper.

See this example.

Damper03

This Damper03 is a simple 3D viscous/nonviscous damper.

• Number of Nodes: 2

• Number of DoFs: 3 (Translation: UX, Translation: UY, Translation: UZ)

Syntax

element Damper01 (1) (2) (3) (4)
element Damper03 (1) (2) (3) (4)
# (1) int, unique tag
