Powder processes are used to produce components from many types of powder compositions and for a wide range of applications. Most processes consist of filling a die, pressing the powder with a appropriate kinematics then ejecting the green part before sintering. In this context, computer modelling of compaction is a practical tool for industry to assist the control of the process. Our research covers modelling and simulation of powder behaviour from loose powder up to ultra high pressure (>10 GPa) and high velocity and high strain rate.
Regarding particle mechanics application most of our research is related to our mining industry. It could be to model a ball charge and its interaction with the structure in a milling process. Or iron ore pellets flow in a silo coupled to the stress field in a single pellet.
