The green compact of uniform density is a fundamental requirement for the production of a good quality and high strength part. Density inhomogeneity can be caused by friction force owing to interparticle movement and relative slip between the powder particles and the die wall. Also, the die geometry and the sequence of punch movements results in a lack of density homogeneity for a compact of complex shape. In this study the mechanical behavior of alumina ceramic powder during maximum applied stress stage to the unloading and after the ejection are analyzed using Finite Element Methods, in whic...
