N2 - Utilizing simulations to visualize and investigate the physical behavior of additive manufacturingAdditive manufacturing powdersPowder processing and their interparticular interactions leads to process improvements in the manufacturing of critical components. Discrete elementDiscrete element modeling analysis (DEM) is used to analyze discontinuous granular particles used in pharmaceuticals, complex aerospace structures, and agricultural processes. Defects caused by vacancy voids during powder distribution processes may lead to manufactured parts with variable densities, reduced mechanical strength and reduce critical components' overall performance. Previous works have been presented to demonstrate methods of powder characterization and analysis techniques to understand how cohesion and moisture affect powder flowability, compaction, and the mechanical properties of manufactured components. Various contact models are compared, and simulations are used to demonstrate how cohesive forces affect the flowability and the distribution of powdersPowder processing in additive manufacturingAdditive maamnufacturing processes.
