Electrical Analogy of Mechanical Model of Polymer Viscoelasticity He Pingsheng, Yang Haiyang, Zhu Pingping Abstract In view of the analogy the of mechanical elements, connecting
ways, static and dynamic mechanical tests with electrical elements, circuit diagram,
instantaneous and alternative circuits, it is found that there are some similarities
between mechanical model in polymer viscoelasticity and electrical circuit, indicating
that it will be very conveniene to get the formula of viscoelasticity by means of
electrical circuit theory.
