Tang-Tat Ng, Auteur ; Chang, Ching S., Éditeur scientifique |This paper presents a sensitivity analysis of the input parameters of a program based on the discrete element method (DEM). Triaxial compression simulations were conducted on an assembly of ellipsoids with two particle shapes. We examine four in[...]

Tang-Tat Ng, Auteur ; Ooi, J. Y., Éditeur scientifique |A new boundary condition has been developed for the discrete element method. This boundary is different from the conventional periodic, rigid, or flexible boundries. This new boundary mechanism was developed to simulate triaxial tests. The new [...]
