Visualization of the meaning of the storage modulus and loss modulus. The loss energy is dissipated as heat and can be measured as a temperature increase of a bouncing rubber ball. Polymers typically show both, viscous and elastic properties and behave as viscoelastic behaviour.
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.
The loss modulus G'' (G double prime, in Pa) characterizes the viscous portion of the viscoelastic behavior, which can be seen as the liquid-state behavior of the sample. Viscous behavior arises from the internal friction between the components in a flowing fluid, thus between molecules and particles.
provided that the shear strain changes according to a sine law, i.e., γ (t ) = γ0 sin ωt. The quantities G and (ω) G (ω) are called the storage and loss moduli, respectively. = GD(ω) = G (ω)2 + G (ω)2 is the dynamic modulus.
The stress and strain are used to calculate a complex ‘shear modulus’, and viscometers will usually report the real (storage modulus) and imaginary (loss modulus) parts of the storage modulus. The model parameters can then be determined by the magnitudes of the stress and strain response, and the time lag between the stress and strain.
G′ is the ‘loss modulus’, which gives the response which is exactly out of phase with the imposed perturbation, and this is related to the viscosity of the material. The relationship between the complex modulus and the material parameter in the viscoelastic models is best illustrated using the Maxwell model.
