5.4: Linear Viscoelasticity
At short times, the stress is at a high plateau corresponding to a "glassy" modulus (E_g), and then falls exponentially to a lower equilibrium "rubbery" modulus (E_r) as the polymer molecules gradually accommodate the strain by conformational extension rather than bond distortion.

6 FAQs about [Storage modulus 20000mpa]
What is the difference between loss modulus and storage modulus?
The storage modulus G' (G prime, in Pa) represents the elastic portion of the viscoelastic behavior, which quasi describes the solid-state behavior of the sample. 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.
What is a storage modulus?
The storage modulus is a measure of how much energy must be put into the sample in order to distort it. The difference between the loading and unloading curves is called the loss modulus, E ". It measures energy lost during that cycling strain. Why would energy be lost in this experiment? In a polymer, it has to do chiefly with chain flow.
Does a loss modulus predominate a storage modulus during a frequency sweep?
Indeed, the loss modulus of samples predominates the storage modulus during frequency sweep. It should be noted that both storage and loss moduli transect at a small frequency, owing to the distortion relaxation of PEO droplets in the incessant PLA medium .
What is storage modulus (E) in DMA?
Generally, storage modulus (E') in DMA relates to Young’s modulus and represents how flimsy or stiff material is. It is also considered as the tendency of a material to store energy .
What is elastic storage modulus?
Elastic storage modulus (E′) is the ratio of the elastic stress to strain, which indicates the ability of a material to store energy elastically. You might find these chapters and articles relevant to this topic. Georgia Kimbell, Mohammad A. Azad, in Bioinspired and Biomimetic Materials for Drug Delivery, 2021
Why do viscoelastic solids have a higher storage modulus than loss modulus?
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.
