Granular model for process simulation of powder forming and powder metallurgy

Tatsuhiko Aizawa

Research output: Contribution to journalArticlepeer-review


The granular modeling has been developed not only to make direct simulation of powder compaction and forming for parts and members but also to consider the coupling between magnetic fields and powder flow for hard copy and powder compaction in the magnetic field. Through those successful analyses, our developed granular modeling is found to be an effective tool to describe powder flow and compaction behavior in actual powder forming. One of the most preferable features to this modeling should be its rational extent ion to fine-grained particle modeling through our developing averaging; this mesoscopic modeling on the basis of the granular modeling can be expected to be available to micro-rheological analysis of aggregated fine particles, various compounds and suspensions.
