| Abstract Scope |
The compaction of metallic and ceramic powders is central to powder metallurgy and advanced ceramics. This talk will give a historical perspective starting from phenomenological equations for densification. A key milestone in understanding this process was a micromechanical model, which emphasized the role of particle rearrangement, plastic deformation, and force chains in densification. This work laid the foundation for physically based models beyond empirical fits. Since then, significant progress has been made in continuum plasticity frameworks, enabling the simulation of densification under complex loading. The rise of discrete element methods has provided additional insight into particle-level behavior and rearrangement dynamics. More recently, multiscale approaches have emerged, incorporating microstructure data from imaging. Despite these advances, challenges remain in predicting springback, damage, and anisotropy. Future models must integrate process–structure–property relationships, include materials kinectics and extend to new material systems like additive-manufactured powders. |
