Random Forces on Obstacles in Channels with Grains: A Mechanical Analogy of Crowd Disastersime of each row of grains. However, in case of initially disordered, loose packing systems, there is an initial relaxation time where force on the obstacle is extremely low, thus allowing the free flow of several grain rows. The temporal force traces have a . character and depend on the initial arrangement of grains.
