Discrete-Element Modeling: Impacts of Aggregate Sphericity, Orientation, and Angularity on Creep Stiffness of Idealized Asphalt Mixtures (2011, background): “Some researchers used the image-based model for simulation of granular materials and evaluated the differences between the idealized aggregate particles and the real aggregate particles for DE simulation (Fu et al. 2008; Wang et al. 2007).”
A simple method to create complex particle shapes for DEM (2008, methodology): “For pavement materials, Wang et al. (2007) proposed a simple clustering method where the irregular volume of a real particle is filled with a regular arrangement of small spheres and afterwards optimised by replacing a group of adjacent spheres by a bigger one (Figure 1a).”
A method to model realistic particle shape and inertia in DEM (2010, background): “[17] proposed a similar clusteringmethod where the volume of an irregular particle is filled with a regular arrangement of spheres but optimized afterwards by replacing groups of adjacent spheres by a bigger one to reduce the total number of spheres and therefore the calculation time.”
