General viscous damping¶
The general viscous damping property implements a viscous damping between the source and target interface.
Definition¶
Source and target interfaces can be chosen arbitrarily.
Parameters¶
General link couplings can be parametrised in two modes: simple and advanced, which are described in the following.
Advanced mode¶
In the advanced mode, the user is prompted to supply four damping matrices,
A list of symbols is shown in following table.

Meaning |
---|---|---|
Load vector to target interface |

Load vector to target interface |

Displacement vector of target interface |

Displacement vector of source interface |
||
Damping matrix coupling target displacement and target load |
||
Damping matrix coupling target displacement and source load |
||
Damping matrix coupling source displacement and target load |
||
Damping matrix coupling source displacement and source load |
Simple mode¶
In the simple mode, a symmetric behaviour between target and source interface is implied. The four damping matrices are replaced by a single damping matrix
