• Density distribution in green pellets of many kinds of Al<SUB>2</SUB>O<SUB>3</SUB> powders was evaluated by energy dispersive X-ray analysis and calculations using a finite element method. Calculated density distributions agreed well with experimental results. Density homogeneity in green pellet has a distinct correlation with a material constant, n, defined in the following yield function.<BR>ρ<SUP>2n</SUP>B<SUP>2</SUP>=((σ<SUB>1</SUB>, -σ<SUB>2</SUB>)<SUP>2</SUP>+(σ<SUB>2</SUB>-σ<SUB>3</SUB>)<SUP>2</SUP>+(σ<SUB>3</SUB>-σ<SUB>1</SUB>)<SUP>2</SUP>)/2+A<SUP>2</SUP>(l-ρ)<SUP>2m</SUP>σ<SUP>2</SUP><SUB>m</SUB><BR>where ρ is relative green density, σ<SUB>i</SUB> is normal stress, σ<SUB>m</SUB> is mean normal stress and B, A, in are material constants.
