Abstract
Various practical consolidation processes such as closed die compaction, hydrostatic compaction and dry rubber press are performed, and relations between stresses and densities are investigated. The stresses required in these compacting processes are compared with the yield stress and fracture stress in uniaxial compression test of green compacts.
For a stress state such that σ2=σ3, the following equation is obtained, which gives a relation between stress and density in compacting process:
?? (a=g1(γ), b=g2(γ);both are the function of γ.)
where σ1, σ2, σ3 are the principal stresses and γ the relative density.
