Link objects are very well suited for modeling the nonlinear force-velocity relationship of viscous damping. The damping properties of nonlinear viscous dampers are based on the Maxwell model of viscoelasticity (Malvern, 1969), and may be specified for each deformational degree-of-freedom (DOF). Those DOF without nonlinear specification will remain linear by using effective stiffness, which may be zero. Additional information is available in the CSI Analysis Reference Manual (Nonlinear Viscous Damper Property, page 257).
Two sets of properties are available to dampers, including:
