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…
Hourglass of constant weight
Volker Becker, Thorsten Poeschel
In contrast to a still common belief, a steadily flowing hourglass changes its weight in the course of time. We will show that, nevertheless, it is possible to construct hourglasse…
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…
Close-packed granular clusters: hydrostatics and persistent Gaussian fluctuations
Baruch Meerson, Manuel Diez-Minguito, Thomas Schwager +1
Dense granular clusters often behave like macro-particles. We address this interesting phenomenon in a model system of inelastically colliding hard disks inside a circular box, dri…
