is studied using where an oscillatory force (stress) is applied to a material and the resulting displacement (strain) is measured. • In purely materials the stress and strain occur in , so that the response of one occurs simultaneously with the other.• In purely materials, there is a between stress and strain, where strain lags stress by a 90 degree ( ) phase lag.Storage modulus is typically represented by the symbol 'G'' and is measured in Pascals (Pa). In viscoelastic materials, the storage modulus varies with temperature and frequency of the applied stress. A high storage modulus indicates that a material behaves more like an elastic solid, while a low storage modulus suggests more liquid-like behavior. [pdf]
