Web2:07. In this video EDEM is used to simulate and analyze a tablet compaction process, using the Edinburgh Elasto-Plastic Adhesion contact model (EEPA) to capture the complex behavior of the powders. EDEM enables users to obtain key micro-mechanical information such as compression forces, stress and porosity and to predict tablet defects.
