As far as I understand stress relaxation function and elastic response functions separated and given in convolution form which provides "strain rate independent" results in qlv application. </p>
<p>Is linear viscoelastic description is strain dependent?</p>
<p>To understand difference, I have generated simple stress relaxation experiment using Abaqus where different strain rates are applied into same model (kept constant a while) which has material property of viscoelastic (Prony ) + hyperelastic (Mooney-Rivlin).</p>
<p>I have used same model but only changed material property hyperelastic to elastic + viscoelastic with different strain rates applied again.</p>
<p>In overall I have see no difference (characteristics of the stress relaxation curve) between two models (visco+hyper VS visco+elastic) .</p>
<p>How can I design a such a experimental model to be able to understand difference between linear viscoelasticity vs quasi linear viscoelasticity in Abaqus?</p>
<p>I hope,I have expressed myself clear enough...</p>
