(77b) Influence of Normal Contact Force Model on Simulations of Sphero-Cylindrical Particles

This study investigates the impact of the contact force model on various aspects of assemblies of rod-shaped particles. DEM normal force models for cohesionless, rod-shaped particles are compared under static and dynamic conditions. Comparisons of the force, overlap, and contact duration frequency distributions are presented. Differences are observed in the overlap and contact duration distributions, but the force distributions are nearly independent of the choice of force model.
