Abstract

A programme on the uniaxial compaction of iron, bronze, ceramic and carbon powders focuses on the compaction mechanism of a simple bushing part during which a complete force balance was recorded. Results show the progressive increase in force as compaction proceeds. A large displacement finite element model employing a Mohr-Coulomb material model was tested against the experimental data and gave good agreement with both tool stresses and compact density levels. A dynamic friction model was also incorporated and found to have a significant effect on both stress and density gradients.
