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. This promising behavior also gives us the interpretation that mechanistically the cytoskeleton possesses a linear log–log relaxation-time spectrum and further that for the storage modulus the cytoskeleton is well modeled by the

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.
Storage modulus G'' represents the stored deformation energy and loss modulus G'''' characterizes the deformation energy lost (dissipated) through internal friction when flowing. 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
The values we get are not quite the same. For this reason, modulus obtained from shear experiments is given a different symbol than modulus obtained from extensional experiments. In a shear experiment, G = σ / ε. That means storage modulus is given the symbol G'' and loss modulus is given the symbol G". Apart from providing a little more

事實上, 儲存模數 G'' (storage modulus) 和 損耗模數 G" (loss modulus) 時 常用來表徵流體,顧名思義,G'' 提供流體彈性特徵的訊息或者形變過程能量之儲存,而 G" 提供流體黏性特徵的訊息或者流動過程能量之損耗。

Storage modulus is the indication of the ability to store energy elastically and forces the abrasive particles radially (normal force). At a very low frequency, the rate of shear is very low, hence for low frequency the capacity of retaining the original strength of media is high.

The elastic modulus for tensile stress is called Young''s modulus; that for the bulk stress is called the bulk modulus; and that for shear stress is called the shear modulus.
