TLDR
In this paper, a 2D discrete model for granular materials with rolling resistance is presented, which consists of a geometrically derived kinematical model, physically based mechanical contact models and locally equilibrated equations governing the motion of the rigid particles; only one additional parameter δ needs to be introduced in the model when compared with the standard discrete element method.About:

Assessment of rolling resistance models in discrete element simulations
TL;DR: A review of the commonly used models for rolling resistance and a more general model is presented in this article, where the robustness of these models in reproducing rolling resistance effects arising from different physical situations was assessed by using several benchmarking test cases.

Discrete numerical model for granular assemblies.

TL;DR: The distinct element method as mentioned in this paper is a numerical model capable of describing the mechanical behavior of assemblies of discs and spheres and is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the objects modelled particle by particle.
