This paper examines a method of adding viscoelastic properties to finite element models by using additional co-ordinates to account for the frequency dependence usually associated with such damping materials. Several such methods exist and all suffer from an increase in order of the final finite mod
We recently reported a new viscoelastic effect, wherein remarkably small quantities of certain high molecular weight polymers inhibit the tendency of water to form a vortex, as it drains from a large tank. This phenomenon is referred to as vortex inhibition (V.I.). Here, we examine the influence of
