Sinterización cerámica por elementos finitos

Abstract

This paper describes and demonstrates the effectiveness of a finite-element procedure to predict the compactation of a green ceramic isostatics pressed plate during sintering process. The approach is based on the conservation of mass principle and requires for its implementation: i) description of the finite element meshes of the green plate when ejected from the press, and ii) the density of the plate after compactation and sintering process. Numerical compactation predictions have been compared with experimental data. The comparisons reveal that the quantitative predictions regarding diameter and height range correlate closely with the measured values showing a difference of 0.52% in diameter and 0.48% in height and a variation on shrinkage of 3.49%. We consider this to be in good agreement, for most practical purposes.
