Kamal K. Kar 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.
Storage modulus and loss modulus are two crucial components of the complex modulus in viscoelastic materials. The storage modulus primarily reflects a material’s ability to store elastic energy upon deformation, indicating its stiffness and solid-like behavior.
While the storage modulus reflects the recoverable strain energy stored, the loss modulus indicates the energy dissipated as heat. Thus, storage modulus is critical for applications requiring materials that retain their shape under stress without plastic deformation. 2. SIGNIFICANCE IN MATERIAL SCIENCE
Elastic storage modulus (E′) is the ratio of the elastic stress to strain, which indicates the ability of a material to store energy elastically.

The slope of the storage modulus curve can indicate not only the operational range of the material but also points at which material failure may happen due to excessive deformation. Understanding these curves allows engineers to better predict the material’s performance in real-world applications. 1. POLYMER INDUSTRY
A high storage modulus indicates that a material behaves more like an elastic solid, while a low storage modulus suggests more liquid-like behavior. The ratio of storage modulus to loss modulus can provide insight into the damping characteristics of a material.
