Mechanical Behaviour of the Ceramic Granule Compact in Cold Isostatic Pressing

Abstract

A new compaction criterion and constitutive equations are proposed for the ceramic granule compact. Compressible behaviour and dilatancy phenomena of the ceramic granule compact can be expressed by these basic equations. Experimental methods are also proposed to determine the material constants necessary for the above-mentioned equations. Based on these equations, a numerical simulation system is developed to estimate the mechanical behaviour of a ceramic granule compact in cold isostatic pressing.
