Under large strains, the stress of the soft gels results from both stretching and orientation of the flexible gel strands irrespectively of the structure of the strands (either individual chains or their fibrous aggregates) and of the nature of the stress (either entropic or enthalpic). Thus, in general, the flexible gel strands would exhibit the weak damping of G(t,γ) when the rates of their shrinkage and rotation are close to each other.
