The storage modulus measures the resistance to deformation in an elastic solid. It's related to the proportionality constant between stress and strain in Hooke's Law, which states that extension increases with force. In the dynamic mechanical analysis, we look at the stress (σ), which is the force.

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. Loss modulus (G") is a measure of the energy dissipated or lost as heat during the shear cycle and represents the viscous behaviour of the.
