Abstract

The knowledge of stress-strain distribution of particulate materials during compression is crucial to the powder processing industries. The finite element technology holds the potential to accurately describe the powder’s stress-strain (pressure-density) response during compression. At present, most of the FEMs are two-dimensional or axisymmetric. which can not precisely model the compaction process. In this project, a 3-D finite element formulation for powder compression is presented. The material parameters (for an elastoplastic model and an elasto-viscoplastic model) for three selected materials have been measured. The flexible boundary cubical triaxial tester was used to determine the constitutive model parameters. The constitutive models were verified using data from cubical triaxial tests.
