Abstract
The cold-compaction densification behavior of silicon nitride (Si3N4) ceramic powder was analyzed using two models: the Shima model and the Cam-Clay model. Triaxial-compression experimental data were used to evaluate these two models. Shima models that used Si3N4 matrix material with different yield stresses were discussed. It is clear that the Cam-Clay model can effectively simulate the cold-compaction densification behavior of Si3N4 ceramic powder. The Shima model that used a very high yield stress for the Si3N4 matrix material slightly overestimated the experimental data, and the Shima model that used the actual yield stress for Si3N4 matrix material largely overestimated that data.
