The discrete element method with application to simulation of granular flow and dynamic fracture of solids

Abstract

Wall stresses are very important parameter in processes run in silos and tanks. DEM method appeared to be a very useful numerical tool in simulation of granular materials [1]. The paper presents the comparison of measured wall stresses exertd by 20,400 pea grains with DEM simulation in the model of silo by the DEMMAT code [2]. Two sensors of 55 mm in diameter were placed on the lateral wall and wall stresses were registered.
