A novel finite strain poro-viscoplastic phenomenological model for cold compacted materials is proposed. The model relies on the three-stage density evolution paradigm and describes the material evolution from loose to solid state. Here this model accounts for rate dependence, elasto-plastic coupling, pressure sensitivity, and transition to full solid state. The model has been implemented, verified, and validated against experimental data available in the literature for copper powder compounds.
