This presentation illustrates an example of a press powder process analysis realized by co-simulation of Ansys® Rocky, Ansys LS-DYNA®, and CYBERNET Multiscale.Sim™.

Manufactured materials from powder go through many processes such as granulation, mixing, compaction, and sintering. Although compaction is one of the most critical processes in determining material properties, there aren't many detailed analyses of this process. The deformation, density, and residual stress distribution of each particle are closely related to the properties of the final product. In many cases, the DEM approach performs calculations at a realistic analysis cost when handling a vast number of particles. However, it's impossible to observe changes in the heterogeneous microstructure in detail because this method treats particles as rigid bodies. Even though the DEM approach is a practical analysis method, it does not provide sufficient information to evaluate the performance of a molded product.
