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 ...

Simulations of dense granular gases without gravity with impact-velocity-dependent restitution coefficient [PDF]
, 2007 We report two-dimensional simulations of strongly vibrated granular materials without gravity. The coefficient of restitution depends on the impact velocity between particles by taking into account both the viscoelastic and plastic deformations of ...

Coefficient of Restitution of a Takraw Ball
International Scholastic Journal of ScienceTakraw is a popular sport in Southeast Asia that is akin to “Foot Volleyball”. It is played by two teams kicking a woven rattan or polymer ball over a net. The coefficient of restitution of a polymer takraw ball impacting the floor at a velocity of 5 ms -

Free cooling and high-energy tails of granular gases with variable restitution coefficient [PDF]
, 2010 We prove the so-called generalized Haff's law yielding the optimal algebraic cooling rate of the temperature of a granular gas described by the homogeneous Boltzmann equation for inelastic interactions with non constant restitution coefficient.

Estimation of the restitution coefficient by strain measurement
EPJ Web of Conferences, 2015 In order to clarify the collision phenomenon of the traffic machine in motion, such as automobile and aircraft, it is necessary to examine not only the deformation and the behavior of composed structural member but also the dynamic characteristic of ...

Particle Collision Study Based on a Rotational Boundary Condition
Journal of Marine Science and Engineering, 2023 The main engineering machinery for the hydrodynamic lifting of seafloor mineral particles is rotor machinery with rotating impeller motion. It is important to study the rebound mechanism of collisions between particles and rotating walls to improve the ...

Geometry of Frictionless and Frictional Sphere Packings [PDF]
, 2001 We study static packings of frictionless and frictional spheres in three dimensions, obtained via molecular dynamics simulations, in which we vary particle hardness, friction coefficient, and coefficient of restitution.
