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.The remaining fundamental quantity is the tangent of the phase lag, (tan (delta)), often simply called "tan delta" and sometimes called the "loss tangent". The in-phase and out-of-phase components of the dynamic modulus are known as the storage modulus and loss modulus, respectively. [pdf]
