A new speed-controlled instrument has been developed for the angle of repose measurements of granular soils. The device proved its reproducibility and repeatability for the measured angle of repose over other types of instruments reported previously. The device has been tested for spherical glass beads (SiO2) and various types of soils and geomaterials. Initially, reported input parameters in the literature for glass beads have been used for EDEM simulation, and the simulated angle of repose matched accurately with the experimental values as shown in the attached files. The next stage is to validate the model for other materials and then study the different mechanical behavior, stabilization, and strengthen of geomaterials from geotechnical engineering and soil mechanics perspectives.

DEM simulations were always considered a black-box and sophisticated coding tools for engineers, especially in our field. However, EDEM made the three-dimensional DEM simulations straightforward for the most of engineering applications with the easiest user-friendly interface and interpretable results. EDEM experience is invaluable for us.
