The soil-rock mixture (SRM) is an excellent composite filler for subgrade, due to its
renewable sources and high structural strength. It is still a challenge to evaluate the impact …

Constitutive relation remains one of the most important, yet fundamental challenges in the
study of granular materials. Instead of using closed-form phenomenological models or …

Abstract Machine learning approaches have found immense potential to revolutionise the
constitutive modelling of granular materials. However, data scarcity poses a significant …

The analytical description of path-dependent elastic-plastic responses of a granular system
is highly complicated because of continuously evolving microstructures and strain …

This paper presents a novel framework for the discrete modeling of the large-scale triaxial
test of rock clasts, considering both the realistic particle shapes and veritable flexible …

Discrete element method (DEM) has been intensively used to study the constitutive
behaviour of granular materials. However, to what extent a real granular material can be …

A series of discrete element method (DEM) triaxial compression simulations on specimens
of an anisometric granular material starting from distinct initial fabric anisotropy states are …

The micro-to macro-scale bearing capacity characteristics of unsaturated fine granular soil
have remained unclear. This study is the first to investigate the capillary suction effect on the …

This paper presents a numerical method to investigate the critical-state behaviors of the soft-
rigid mixture via DEM simulation. First, according to a series of laboratory tests of sand …

This study proposes an automated calibration procedure for bond parameters in bonded
discrete element modelling. By exploring the underlying physical correlations between …
