This paper describes an experimental study examining the influence of the mechanical and
geometrical properties of the constituent grains on the overall material response of …

Internal instability is a form of internal erosion in broadly graded cohesionless soils in which
fine particles can be eroded at lower hydraulic gradients than predicted by classical theory …

Understanding the extent to which discrete element method (DEM) simulations can capture
the critical state characteristics of granular materials is important to legitimize the use of DEM …

Previous research studies have used either physical experiments or discrete element
method (DEM) simulations to explore, independently, the influence of the coefficient of inter …

This research pioneers a stochastic discrete-element method (DEM) by integrating the
probability density evolution method (PDEM), offering a novel approach to connect particle …

Over the past 50 years, experimental studies have repeatedly demonstrated that the
mechanical behaviour of sand is sensitive to the material fabric, that is, the arrangement of …

Significant uncertainty exists in granular materials, as demonstrated by experimental and
simulation studies. Quantifying this uncertainty by integrating refined discrete element …

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 …

In the study we experimentally examine the influence of elastic properties and surface
morphology on the inter-particle friction of natural soil grains. The experiments are …

This paper considers factors influencing the fabric of bimodal or gap-graded soils. Discrete
element method simulations were carried out in which the volumetric fines content and the …
