AbstracL We present an implemenlalion of realistic static friction in molecular dynamics (MD) simulations of granular particles. In our model, to break contact between two particles, one has to apply a Bnile amount of force, determined by the Coulomb criterion. Using a Wo.dimmsional model, we show that piles generated by avalanches have a @e angle of repose 8, (finite slopes). Furthermore, these piles are stable under tilting by an angle smaller lhan a non-zero tilting angle h, showing that 8 R… CONTINUE READING
