Effect of the coefficient of restitution and friction in the granular Leidenfrost effect in the absence of gravity. A numerical study [PDF]
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 ...

Impact of a pressurized membrane: Coefficient of restitution
Pressurized membranes are usually used for low cost structures (e.g., inflatable beds), impact protections (e.g., airbags), or sport balls. The last two examples deal with impacts on the human body. Underinflated protective membranes are not effective whereas overinflated objects can cause injury at impact. The coefficient of restitution represents the

Coefficient of Restitution of Wet Tennis Balls [PDF]
The coefficient of restitution of a damp tennis ball is of interest to tennis players. Using a spray bottle, water was added to a tennis ball and the mass of water on the wet ball was determined. The ball was then dropped from a fixed height of 0.86 m.

Influence of the coefficient of restitution on the classification of granite sand using an elutriator [PDF]
The objective of this work was to measure the coefficient of restitution of fine granite sand dust (passing sieve ASTM N°30) and to study its influence on the prediction of classification parameters in an elutriator device.

Effects of the impact angle on the coefficient of restitution in rockfall analysis based on a medium-scale laboratory test [PDF]
The reliability of a computer program simulating rockfall trajectory depends on the ascertainment of reasonable values for the coefficients of restitution, which typically vary with the kinematic parameters and terrain conditions.

Air Pressure and Coefficient of Restitution of a Ball [PDF]
The relationship between the pressure of a ball and its coefficient of restitution was investigated, a rubber handball was inflated to eight varying air pressures and then dropped from a constant height. With measurements of its mass, circumference,

Coefficient of Restitution Interpreted as Damping in Vibroimpact [PDF]
During impact the relative motion of two bodies is often taken to be simply represented as half of a damped sine wave, according to the Kelvin-Voigt model. This is shown to be logically untenable, for it indicates that the bodies must exert tension on one another just before separating.
