摘要：
A new elastic/viscoplastic constitutive model for compaction of powder materials has been proposed. The model can be determined from a few conventional compression triaxial rests. In this model the irreversible volumetric strain is taken as work hardening parameter The model prediction matches reasonably well the experimental data.
