Coefficient of restitution for wet particles [PDF]
Physical Review E, 2012 The influence of a wetting liquid on the coefficient of restitution (COR) is investigated experimentally by tracing freely falling particles bouncing on a wet surface. The dependence of the COR on the impact velocity and various properties of the particle and the wetting liquid is presented and discussed in terms of dimensionless numbers that ...

Interval of restitution coefficient for chattering in impact damper
Journal of Low Frequency Noise, Vibration and Active Control, 2022 Based on the impact damper, a dynamic model of a non-fixed constrained collision system was established. The coefficient of restitution is used as the main control parameter to analyze the system’s periodic movement and its bifurcation region.

Coefficient of restitution of colliding viscoelastic spheres [PDF]
Physical Review E, 1999 We perform a dimension analysis for colliding viscoelastic spheres to show that the coefficient of normal restitution $ $ depends on the impact velocity g as =1- _1g^{1/5}+ _2g^{2/5}\mp..., in accordance with recent findings. We develop a simple theory to find explicit expressions for coefficients _1 and _2.

Ratio of Loss and Storage Moduli Determines Restitution Coefficient in Low-Velocity Viscoelastic Impacts [PDF]
, 2020 Impact tests are an important tool to analyze dynamic material properties of viscoelastic media in technology and biology. In this context, rigorous contact mechanical models of the collision problem are necessary to adequately interpret data from impact

Effect of the coefficient of restitution and friction in the granular Leidenfrost effect in the absence of gravity. A numerical study [PDF]
EPJ Web of Conferences, 2021 In this study the granular Leidenfrost effect in the absence of gravity is investigated numerically by means of the discrete element method. Apart from identifying the phenomena, a parametric study to quantify the influence of the coefficient of ...

The anomalous behavior of coefficient of normal restitution in the oblique impact [PDF]
, 2004 The coefficient of normal restitution in an oblique impact is theoretically studied. Using a two-dimensional lattice models for an elastic disk and an elastic wall, we demonstrate that the coefficient of normal restitution can exceed one and has a peak ...
