Storage modulus of spinning solution

The storage modulus, symbolized as G’ (G-prime), represents the elastic portion of this response. The strain is the amount of deformation in the material, such as the change in length in an extensional experiment, expressed as a fraction of the beginning length. The rheology of the aqueous PEO solution and PEO/SPI blends (flow curves, loss modulus, and storage modulus) was then analyzed. Because a °uid can never remember times in the future, G(t) = 0 if t < 0. Physically, you would also expect that more recent strains would be more important than those from longer ago, so in t > 0, G(t) should be a decreasing function. It defines the relationship between Stress Stress is defined as a level of force applied on a sample with a well-defined cross section.
