When we define a viscoelastic material model as a combination of elastic or hyperelastic material and Prony series, what do the elastic/hyperelastic constants represent – the long term or the instantaneous response?

      The elastic or the hyperelastic terms represent the instantaneous (at t=0 s) response, or in other words, it represents the high strain-rate response.
