Abstract
The 3D discrete element approach is used for the computational investigation of the problem on pressure exerted by granular material on the bottom and walls of a cylindrical container. Dry friction between the granular material particles and friction on the container walls are taken into account. The particles have spherical shape with the assigned radial distribution. The authors analyze the effect of filling method on stress state of granular medium. Accuracy of Janssen’s hypotheses is estimated in engineering problem formulation.
