Compaction simulation
Compaction simulation is the modelling of granular matter when compressed into a dense state that is achieved through the reduction of the air void. The term is also commonly used to mean compaction using a compaction simulator. This is a high performance programmable servo-controlled press for simulating production presses, typically in the pharmaceutical, catalyst, battery and magnet industries. Three stages are included in the compaction process those are filling or packing, compaction and ejection. During the compaction process, if the loading pressure is increasing straightly, the powder assembly will experience three stages. First of all, particles are filling the voids and set up contacts with the adjacent particles. This stage is termed rearrangement stage. After most contacts are set up, the initial compaction started. Elastic deformation and plastic deformation happens and the loading pressure increases sharply. The third stage is breakage where the particles breaks into fragments. Discrete element method (DEM) is an explicit numerical model capable of tracking the motion and interaction of individual modeled particles. DEM has enhanced rapidly our understanding of granular system by producing quantitative predictions rather than only qualitative description, increased our insight into particle assemblies by providing both microscopic and macroscopic information.…
