Numerical simulations of the maximum angle of stability of bi-disperse cohesive granulates

We performed molecular dynamics simulations of the maximum angle of stability of a bi-disperse granulate with cohesion (either springs or constant inter-particular forces) in a rotating drum. Segregation has been avoided by computing only the first angle of maximum stability after the rotating drum...

Description
Summary:We performed molecular dynamics simulations of the maximum angle of stability of a bi-disperse granulate with cohesion (either springs or constant inter-particular forces) in a rotating drum. Segregation has been avoided by computing only the first angle of maximum stability after the rotating drum started its rotation. The results show that larger cohesive forces have to be applied in order to recover the same avalanche angle as for a mono-disperse granulate.
