Fig. 5From: Influence of Elastic Stiffness and Surface Adhesion on Bouncing of NanoparticlesCoefficient of restitution. Dependence of the coefficient of restitution, e, on collision velocity, v, for a strongly (γ=2.32 J/m2) (a) and a weakly (γ=0.89 J/m2) (b) adhesive surface. The bulk modulus is identical in both cases, B=940.8. Symbols denote simulation results, while the curve is a fit to the JKR prediction, Eq. (6), with α=0.86 (a) and 0.95 (b)Back to article page
