Abstract: Abstract Whereas size segregation is a fairly common phenomenon in granular material research, up to now shape segregation was has not been observed. We present simulations of bidisperse shaped (elliptic and round) granular particle systems which exhibit a demixing of round and elongated particles. The effect is not only controlled by the particle elongation, but also by the Coulomb friction coefficient in the system.
