Basics of rheology | Anton Paar Wiki

Viscoelastic solids with G'' > G'''' have a higher storage modulus than loss modulus. This is due to links inside the material, for example chemical bonds or physical-chemical interactions (Figure 9.11). On the other hand, viscoelastic liquids with G'''' > G'' have a higher loss modulus than storage modulus.
