Viscoelasticity

In materials science and continuum mechanics, viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied. Elastic materials strain when stretched and immediately return to

The agent decisions (regarding investment in generation capacity) are taken every year, after the market is cleared on an hourly basis. After market clearing, a load duration curve [129] is calculated for 20 segments (or load blocks) to capture the variation of load over the year, as shown in Fig. 1, which is used for investment decisions in

Storage Modulus

Storage modulus is the indication of the ability to store energy elastically and forces the abrasive particles radially (normal force). At a very low frequency, the rate of shear is very low, hence for low frequency the capacity of retaining the original strength of media is high. As the frequency increases the rate of shear also increases
