Storage modulus measured by rheometer

The values measured by the rheometer (deflection angle, torque, and phase shift) together with the conversion factors for the measuring system now give all necessary data to calculate the required rheological parameters such as the storage modulus G’ or loss modulus G’’. This means that in a viscosity measurement the rheometer presets a certain current that correlates to a defined torque. Storage Modulus (E’ or G’): The storage modulus is a measure of the stored energy in a material during deformation, reflecting its elastic or ‘solid-like’ behavior. Basic consideration of the experimental methods using parallel-plate oscillatory rheometer and step-by-step guidelines for the estimation of the power law dependence of storage, G ′ and loss, G ″ modulus as well as the estimation of the relaxation time at 𝑓 𝐺 ′ − 𝐺 ′ ′ c r o s s at terminal zone.
