Integrating Simulation and Experimentation for Optimized Compaction Powder Forming: A Study on RVE Size, Friction, and Particle Size Distribution

This work comprehensively represents multi-particle finite element simulations for powder compaction, including examining representative volume element (RVE) size, friction effects, and particle distribution. The analysis provides valuable insights into the correlation between RVE size and relative density, facilitating a comprehensive understanding of the sensitivity of process parameters to relative density. Furthermore, the research investigates the impact of particle size distribution. Moreover, the study investigates the influence of friction between powder particles and the die wall. Results demonstrate that increased friction leads to a significant reduction in relative density.
