Popis:	An analytical expression of the coefficient of restitution for viscoelastic materials is derived for the viscous-dominant case, such as collisions of polymeric melt. The recently proposed normal impact force model between two colliding viscoelastic droplets is employed. To analytically solve the nonlinear differential equation of deformation caused by the other droplet, a perturbation method is applied. By combining the forward collision and the inverse collision, we can get an analytical expression for the coefficient of restitution, which can also be used to further analyze other properties related with the viscoelasticity.
