3 Linear viscoelasticity

We can see that if G00 = 0 then G0 takes the place of the ordinary elastic shear modulus G0: hence it is called the storage modulus, because it measures the material''s ability to store elastic energy. Similarly, the modulus G00 is related to the viscosity or dissipation of energy: in other words, the energy which is lost.

Storage Modulus

The storage modulus G ′ from the data and the SGR model match each other well even up to ω / Γ 0 ∼ 1 where we cannot expect good agreement.
