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".
For the purposes of carrying out a static load stress analysis can I assume that storage modulus is roughly equivalent to shear modulus and therefore elastic modulus of the material is...

In materials science, shear modulus or modulus of rigidity, denoted by G, or sometimes S or μ, is a measure of the elastic shear stiffness of a material and is defined as the ratio of shear stress to the shear strain: [1]
Dynamic modulus (sometimes complex modulus[1]) is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation).
3. 剪切模量G (Shear Modulus) 剪切模量是指剪切应力与剪切应变之比。 G=剪切弹性模量G=切变弹性模量GG,材料的基本物理特性参数之一,与杨氏 (压缩、拉伸)弹性模量E、泊桑比ν并列为材料的三项基本物理特性参数,在材料力学、弹性力学中有广泛的应用。
Calculate Young''s Modulus from the Bulk Modulus See Also Summary The following equations demonstrate the relationship between the different elastic constants, where: E = Young''s Modulus, also known as Modulus of Elasticity G = Shear Modulus, also known as Modulus of Rigidity K = Bulk Modulus = Poisson''s Ratio
G'' 储能模量> G'''' 耗损模量：该体相 更偏向于 弹性固体（elastic solid)的特性, 粘性流体 (Viscous fluids）的特性弱于弹性固体的特性。
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.

In materials science, shear modulus or modulus of rigidity, denoted by G, or sometimes S or μ, is a measure of the elastic shear stiffness of a material and is defined as the ratio of shear stress to the shear strain: where = shear strain. In engineering , elsewhere is the initial length of the area.

Storage modulus is measured for materials like polymers that have an elastic and viscous component. I suspect for the data you see it reports storage modulus, which is elastic storage modulus, not shear storage modulus. It is likely reported as a static modulus, so would assume it to be equal to the elastic modulus, E, or close to it.
For materials within the elastic range the shear strain is proportional to the shear stress producing it, i.e. The constant G is termed the modulus of rigidity or shear modulus and is directly comparable to the modulus of elasticity used in the direct stress application. The term modulus thus implies a ratio of stress to strain in each case.
By convention we de ̄ne the complex shear modulus, G¤, as: G¤ = i! G(s) exp [¡i!s] ds; are called the storage modulus G0 and the loss modulus G00. This gives = [G0 sin (!t) + G00 cos (!t)] = G0°(t) + _°(t): ! Now a purely viscous °uid would give a response
This study is also used to understand the microstructure of the abrasive media and to infer how strong the material is. Storage modulus (G') is a measure of the energy stored by the material during a cycle of deformation and represents the elastic behaviour of the material.
