Investigating the effects of Fourier-based particle shape on the shear behaviors of rockfill material via DEM

This report investigates the effects of Fourier-based particle shape on the macroscopic and microscopic shear responses of rockfill material via a series of numerical biaxial compression tests. The multi-disk method is employed to model two-dimensional irregular rockfill particles. The macroscopic characteristics, including the shear strength and the dilatancy response, and the microscopic characteristics, including the contact force, the...
