Finite Element Analysis of Wet Granule Compression Using a Density-Dependent Modified Model

Abstract

Prediction of wet granule compression process is significant for the industry. In this study, finite element method (FEM) simulation using the modified density-dependent Drucker-Prager Cap model (mDPC model) is performed to improve the deviation of actual stress values from calculated stress values of wet granules under compression. FEM simulation using the DPC model is also performed as a reference. The results show that the axial stress at the top surface and the radial stress of the wall obtained from the FEM simulation using the mDPC model were more consistent with the experimental values than those obtained by the DPC model.
