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…
Fractal Substructures due to Fragmentation and Reagglomeration
Dietrich E. Wolf, Thorsten Poeschel, Thomas Schwager +2
Cohesive powders form agglomerates that can be very porous. Hence they are also very fragile. Consider a process of complete fragmentation on a characteristic length scale ,…
Fractal Substructure of a Nanopowder
Thomas Schwager, Dietrich E. Wolf, Thorsten Poeschel
The structural evolution of a nano-powder by repeated dispersion and settling can lead to characteristic fractal substructures. This is shown by numerical simulations of a two-dime…
Coefficient of tangential restitution for the linear dashpot model
Volker Becker, Thomas Schwager, Thorsten Poeschel
The linear dashpot model for the inelastic normal force between colliding spheres leads to a constant coefficient of normal restitution, const., which makes this model very p…
Coefficient of Restitution for Viscoelastic Spheres: The Effect of Delayed Recovery
Thomas Schwager, Thorsten Poeschel
The coefficient of normal restitution of colliding viscoelastic spheres is computed as a function of the material properties and the impact velocity. From simple arguments it becom…
Coefficient of restitution and linear dashpot model revisited
Thomas Schwager, Thorsten Poeschel
With the assumption of a linear-dashpot interaction force, we compute the coefficient of restitution as a function of the elastic and dissipative material constants, k and gamma by…
