# Dashpots

 Dashpot elements: can couple a force with a relative velocity; in Abaqus/Standard can couple a moment with a relative angular velocity; can be linear or nonlinear; if linear, can be dependent on frequency in direct-solution steady-state dynamic analysis; can be dependent on temperature and field variables; and can be used in any stress analysis procedure. The terms “force” and “velocity” are used throughout the description of dashpot elements. When the dashpot is associated with displacement degrees of freedom, these variables are the force and relative velocity in the dashpot. If the dashpots are associated with rotational degrees of freedom, they are torsional dashpots; these variables will then be the moment transmitted by the dashpot and the relative angular velocity across the dashpot. In dynamic analysis the velocities are obtained as part of the integration operator; in quasi-static analysis in Abaqus/Standard the velocities are obtained by dividing the displacement increments by the time increment. The following topics are discussed:
