This report explores the effects of particle shape and content of fines on the shear behavior
of sand-fines mixtures using a two-dimensional discrete element method. The contributions …

A series of monotonic and cyclic triaxial shearing tests on Toyoura sand are simulated by
discrete element method (DEM) incorporating rolling resistance. The input parameters are …

A series of monotonic and cyclic triaxial shearing tests are simulated by discrete element
method (DEM) to explore packing density, critical state, and liquefaction resistance of sand …

This report investigated the effects of irregular particles on macroscopic and microscopic
behaviour under triaxial compression tests for a range of various roundnesses. A multi …

Mixtures of sand and rubber particles were simulated using DEM. Rubber content varied
from 0% to 50%. The numerical samples were sheared in the range of 10− 5–10− 2% of ε 1 …

The strain characteristic and load transmission of mixed granular matter are different from
those of homogeneous granular matter. Cyclic loading renders the mechanical behaviours …

This contribution considers the critical time increment (Δt crit) to achieve stable simulations
using particulate discrete element method (DEM) codes that adopt a Verlet-type time …

The critical state (CS), the anchor concept in the critical state soil mechanics (CSSM)
framework, has been comprehensively evaluated in triaxial stress conditions, where all the …

Saturation conditions play a significant role in the mechanical behavior of granular material
and the evolution of an interparticle contact system during the loading process. Using data …

The fragments from crushed rock are initially very angular. The erosion process causes the
fragment shape to evolve from angular to well rounded and affects the mechanical …
