Abstract
The effect of die wall friction on the densification of metal powders under die pressing is studied. The elastoplastic constitutive equations based on the yield functions by Fleck and Gurson and by Shima and Oyane were implemented into a finite element program to simulate die compaction processes. The friction coefficient between the powder and the die wall was determined from the relationship between the compaction pressure and the ejection pressure. Finite element calculations were compared with experimental data for densification and deformation of 316L stainless steel powder and D7 tool steel powder under single and double action die pressing.
