Copaction Behaviour of Ceramic Powder in CIP

Abstract

An alumina (Al₂O₃) powder is isostatically compacted at room temperature and the density ratio achieved is measured. The mean density is compared in terms of the size of the compact, however, there is no significant size effect. The characteristics of compaction behaviour of ceramic powder is quite different from that of metallic powders. Taking account of the difference into the constitutive equations for the powder, Lhe rigid-plastic finite element analysis of CIP is carried out and the results are compared and discussed.
