Rolling friction and bistability of rolling motion
Thorsten Poeschel, Thomas Schwager, Nikolai Brilliantov +1
The rolling motion of a rigid cylinder on an inclined flat viscous surface is investigated and the nonlinear resistance force against rolling, , is derived. For small veloc…
Rigid body dynamics of railway ballast
Thomas Schwager, Thorsten Poeschel
A method for the discrete particle simulation of of almost rigid, sharply edged frictional particles, such as railway ballast is proposed. In difference to Molecular Dynamics algor…
Is there a critical acceleration for the onset of convection?
Thorsten Poeschel, Thomas Schwager
Suppose granular material is shaken vertically with z(t)=A_0 cos(ω_0 t). Can we expect to find convection if A_0ω_0^2 < g? By means of theoretical analysis and computer simulation…
Contact of Viscoelastic Spheres
Thomas Schwager, Thorsten Poeschel
In a recent paper an implicit equation for contacting viscoelastic spheres was derived (Brilliantov et al. PRE 53, 5382 (1996)). Integrating this equation it can be shown that the…
Vertically shaken column of spheres. Onset of fluidization
Simon Renard, Thomas Schwager, Thorsten Poeschel +1
The onset of surface fluidization of granular material in a vertically vibrated container, z=A cos(ωt), is studied experimentally. Recently, for a column of spheres it has been the…
