Determination of the Bulk Flexure Resistance via coupled FEM-DEM Simulation

The bulk material on a belt conveyor deforms itself due to the run through idler stations. The deformation results in energy losses which are summarised in the bulk solid flexure resistance. The right understanding of the interaction between bulk material and idler stations is important for the pred…read more
