Microstructure Evolution During Compaction Of Powder Blends, Ayush Giri, Marcial Gonzalez, Yasasvi Bommire
The Summer Undergraduate Research Fellowship (SURF) Symposium
Powder compaction is a manufacturing technology used to transform powder particles into a solid material with unique anisotropic microstructure and low porosity. It is widely used by pharmaceutical companies to manufacture tablets with desired properties. These properties are the result of the microstructure obtained during the compaction process. Therefore, it is imperative to understand the mechanics underneath the constituent granular particles that eventually contribute to properties of the manufactured tablets. Computational simulation tools have been developed in the past to study powder compaction for pharmaceutical tablets. However, most of the already existing tools limit their scope to study individual particles …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Powder compaction is the process of transforming granular media into a solid body with a high relative density (low porosity) and a unique anisotropic microstructure. It is critical to understand the physical mechanisms of the compaction process in order to identify powder properties and optimal process parameters for achieving desired properties of the final product. Tools that can simulate particle rearrangement and deformation during the compaction process are usually developed to guide such fundamental understanding. This study aims at understanding powder compaction using particle mechanics approach. Specifically, it employs the nonlocal contact formulation to predict the contact behavior of a …
