Suitability of parameters and models in the discrete element method for simulation of mesoscale powder indentation experiments
The Discrete Element Method (DEM) has been shown in the literature to be able to match the resultsof certain experimental powder process such as shear cell and angle of repose tests. In this work wetry to discover which models and parameters are required by the DEM to simulate a mesoscale process.This work compares 2D and 3D simulations, linear and Hertzian stiffness models, friction and cohesionand several values of stiffness parameter. Using 3D models with friction and higher stiffness valuesproduced the most similar behavior to the experiments. Spectral results show the scales of the particlerearrangements were reproduced by the DEM and independent of parameters and models considered in this work.

Abstract
The Discrete Element Method (DEM) has been shown in the literature to be able to match the resultsof certain experimental powder process such as shear cell and angle of repose tests. In this work wetry to discover which models and parameters are required by the DEM to simulate a mesoscale process.This work compares 2D and 3D simulations, linear and Hertzian stiffness models, friction and cohesionand several values of stiffness parameter. Using 3D models with friction and higher stiffness valuesproduced the most similar behavior to the experiments. Spectral results show the scales of the particlerearrangements were reproduced by the DEM and independent of parameters and models considered in this work.
