DEM Simulation of Bead Packs as Fillers in Thin-wall Tube Push Bending Process
The bead pack,as filler,has been introduced to thin-wall tube bending process.The pressure transmission,flowing and deformation characteristics of different bead pack systems are simulated during tube push bending with discrete element method (DEM).The simulations are conducted respectively in different conditions including friction and frictionless,bead pack systems with the same size and different sizes.As a result,the friction coefficient is the major parameter in the deformation of bead packs.Consequently the bead packs can be used as fillers to improve thin-walled tube push bending process,especially the ultra-thin-wall tube bending.
