Notes:
Powder consolidation constitutes an important step in the manufacture of products ofhigh quality and precision. To obtain these components, with desired forms and final mechanicalproperties, it is of extreme importance to have knowledge about the processes to obtain powders,compacting and sintering. The objective of this work is to verify which model, obtained from theliterature, better describes the compaction densification behavior of iron powder in closed-die.Doraivelu’s criterion was carried through the method of the finite elements with the implementationof an elastoplastic model with hardening. The influence of the yield function coefficient against therelative density was evaluated, as well as, the yield function in the hydrostatic space
