Nonlinear dashpot damping - NLdashpt
This is a two-node damping element, providng damping in all six global degrees of freedom. Damping in each degree of freedom is modelled through a Force-Velocity relationship defined by one of the available response curves. For the definition of the element the user needs to define a response curve for the modelling of the damping action in each direction.
Currently, twenty nine response curves are selectable within the Element Class dialog box, whenever a nonlinear link element type is selected.
