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…
Adhesive interactions of viscoelastic spheres
Nikolai V. Brilliantov, Thorsten Poeschel
We develop an analytical theory of adhesive interaction of viscoelastic spheres in quasistatic approximation. Deformations and deformation rates are assumed to be small, which allo…
Bistability and noise-enhanced velocity of rolling motion
Thorsten Poeschel, Nikolai V. Brilliantov, Alexei Zaikin
We investigate the motion of a hard cylinder rolling down a soft inclined plane. The cylinder is subjected to a viscous drag force and stochastic fluctuations due to the surroundin…
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…
Force Distribution and Comminution in Ball Mills
Volkhard Buchholtz, Thorsten Poeschel
The motion of granular material in a ball mill is investigated using molecular dynamics simulations in two dimensions. In agreement with experimental observations by Rothkegel [1]…
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…
