Rather than making the rings out of plastic, one possibility is to make them out of used grain from breweries. The rings would break down in two to three months and wouldn’t harm wildlife. It’s a win-win situation because the breweries don’t have to pay to have the grain thrown away and the new ...
We compute the net force exerted on each grain by capillary pressure, including cohesion at grain contacts supporting pendular rings. We combine those forces to determine the movement of grains using: a) a kinematic model; b) a rigorous model where mechanical stress and elastic properties of grains are included ...
