This paper deals with a computational analysis of the influence of the pressing method and part geometry on the final density distribution in the cold compaction process of ceramic alumina powders. The analysis is based on the explicit finite-element model proposed and validated in a previous study.The mechanical behavior of the processing material is described using a multisurface elastoplastic model, the modified Drucker–Prager/Cap model.

Abstract
This paper deals with a computational analysis of the influence of the pressing method and part geometry on the final density distribution in the cold compaction process of ceramic alumina powders. The analysis is based on the explicit finite-element model proposed and validated in a previous study.The mechanical behavior of the processing material is described using a multisurface elastoplastic model, the modified Drucker–Prager/Cap model.File in questo prodotto:
