Scaling granular material with polygonal particles in discrete element modeling

Ahmadi, A., Larsson, S. and Wersäll, C. (2023) Scaling granular material with polygonal particles in discrete element modeling. Particuology 75: 151-164. doi.org/10.1016/j.partic.2022.07.005

Despite advancements in computational resources, the discrete element method (DEM) still requires considerable computational time to solve detailed problems, especially when it comes to the large-scale models and the particle shape. In this study, the effect of particle scalping on the shear behavior of granular material is explored. The results show that particle scalping can simulate the correct shear behavior of the model with significant improvement in computational time.
