This work reviews the main techniques to model dynamical systems with contact-impact
events. Regularized and non-smooth formulations are considered, wherein the fundamental …

We discuss methods to compute the flow of non-Brownian, non-cohesive, and non-spherical
rigid bodies immersed in a single homogeneous fluid. We address both the case of …

The contact dynamics (CD) method is presented as a discrete element method for the
simulation of nonsmooth granular dynamics at the scale of particle rearrangements where …

When velocity jumps are occurring, the dynamics is said to be nonsmooth. For instance, in
collections of contacting rigid bodies, jumps are caused by shocks and dry friction. Without …

Discrete element simulation provides some insight into the alteration of railway ballast after
repeated train passings. The present Part 1 is devoted to a 2D model of this granular layer …

We present a systematic investigation of the morphology and space-filling properties of
polydisperse densely packed granular media in two dimensions. A numerical procedure is …

We investigate a class of granular materials characterized by the possibility of interlocking
between the particles. The interlocking is modeled by its effect through rolling resistance …

We present a systematic numerical investigation concerning the combined effects of sliding
friction and particle shape (ie, angularity) parameters on the shear strength and …

By means of two-dimensional numerical simulations based on contact dynamics, we present
a systematic analysis of the joint effects of grain shape (ie, grain elongation) and system size …

Assessing the shear strength of coarse granular soils is challenging because testing devices
in the laboratory often limit the maximum particle size (d max). Although engineering …
