Predicting density distribution in Green compacts using finite element simulations

Finite element simulation of the rigid die compaction of metal powders can significantly help designers avoid some of the typical problems they face such as the high density gradients within compacted parts and related cracking. In this paper, the modeling of an axisymmetric flanged part using fini...
