The Discrete Element Method (DEM) and the Bonded Particle Model (BPM) were applied for the investigation. To describe the mechanical behavior of granules during compression, an elastic-plastic bonded model was implemented, in which the moisture content is linked to the properties of the bonds. A good agreement was reached between experiments and simulations for the second and third stages of compaction. Herein, we obtained a mathematical model that links moisture, bond behavior during rupture, and porosity after compression. Different experimental studies have validated the model with high-achieving correspondence between the experiments and simulations. Thus, the proposed simulation methodology proved effective in predicting the porosity of the particles' bulk after uniaxial compaction.en0032-59102023Elsevier B.V.CompressionDiscrete element methodMoisturePorcelain raw materialsPorositySpray-dried granulesPhysicsTechnologyEngineering and Applied OperationsJournal Article10.1016/j.powtec.2023.118863Journal Article
