This paper presents a novel two-dimensional (2D) discrete model for granular materials with
rolling resistance. The salient features of our formulation are: it consists of a geometrically …

A comprehensive comparison between the Hertz–Mindlin model and the linear spring model
in true triaxial shear simulations of granular soils was conducted using the discrete-element …

Both linear-spring–dashpot (LSD) and non-linear Hertzian-spring–dashpot (HSD) contact
models are commonly used for the calculation of contact forces in Discrete Element Method …

A discrete element modelling of bonded granulates and investigation on the bond effect on
their behaviour are very important to geomechanics. This paper presents a two‐dimensional …
