Oblique Impact of Frictionless Spheres: On the Limitations of Hard Sphere Models for Granular Dynamics
Patric Mueller, Thorsten Poeschel
When granular systems are modeled by frictionless hard spheres, particle-particle collisions are considered as instantaneous events. This implies that while the velocities change a…

Coefficient of Restitution as a Fluctuating Quantity
Marina Montaine, Michael Heckel, Christof Kruelle +2
The coefficient of restitution of a spherical particle in contact with a flat plate is investigated as a function of the impact velocity. As an experimental observation we notice n…

Collision of Viscoelastic Spheres: Compact Expressions for the Coefficient of Normal Restitution
Patric Mueller, Thorsten Poeschel
The coefficient of restitution of colliding viscoelastic spheres is analytically known as a complete series expansion in terms of the impact velocity where all (infinitely many) co…
