How can I model QLV (Quasi Linear Viscoelasticity proposed by Fung) in Abaqus ?

 If I have generate material vith viscoelastic (prony series) + hyperelastic properties, is this setup belongs to quasi-linear viscoelasticity ?

 If so, How can I model linear viscoelasticity?

Can anyone explain what is main difference between Linear Viscoelasticity vs qlv (Quasi linear Viscoelasticity) proposed by Fung.  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.  

Is linear viscoelastic description is strain dependent?
