Hi all

This is my first time here and I'm hoping first that I have reached the right forum for my question and that someone out there can help me! I am trying to model the energy dissipation of what is effectively a mass spring damper where the spring and damper are modelling a polymer. I have chosen the Kelvin-Voigt model for this which requires a viscosity to calculate. I have tried looking for viscosity values but there seems to be none that exist for solid polymers, only melt and solution viscosities for polymers in their liquid state used for injection moulding and such. So have I misunderstood viscoelasticity and am using the wrong model or are the viscosity values I have found applicable to their solid states? Or something else that I have not considered?
