Granular Toppling and Piling
Granular Toppling and Piling
This Demonstration shows the toppling and piling tendencies of ideal grains of uniform geometry under ideal conditions. Toppling is observed both in the red grain box and after the grains hit the ground. At the confluence of grains above the grain box slit friction effects can give rise to arching, forcing the grains to fall through the slit at a nonuniform rate.
