Connector damping behavior

Connector damping behavior:

  • can be of a dashpot-like viscous nature in transient or steady-state dynamic analyses;

  • can be of a “structural” nature, related to complex stiffness, for steady-state dynamics procedures that support non-diagonal damping;

  • can be defined in any connector with available components of relative motion;

  • can be specified for each available component of relative motion independently, in which case the behavior can be linear or nonlinear for viscous nature damping;

  • can be specified as dependent on relative positions or constitutive motions in several local directions for viscous nature damping; and

  • can be specified for all available components of relative motion as coupled damping behavior.

The directions in which the forces and moments act and the relative velocities are measured are determined by the local directions as described in Connection-type library for each connection type. In dynamic analysis the relative velocities are obtained as part of the integration operator; in quasi-static analysis in Abaqus/Standard the relative velocities are obtained by dividing the relative displacement increments by the time increment.
