The relationship between critical state and particle shape corresponds to the most
fundamental aspect of the mechanics of granular materials. This paper presents an …

This paper presents a micro-mechanical study on the characteristics of shear-induced
anisotropy in granular media. Based on three-dimensional Discrete Element Method (DEM) …

This paper describes a fundamental study to explore the role of particle shape in the shear
behaviour of mixtures of sand and fine particles (fines) through macro-scale and grain-scale …

The mechanical behaviors of granular soils at different initial densities and confining
pressures in the drained and undrained triaxial tests are investigated micromechanically by …

Despite the significant progresses in discrete-based numerical studies of granular materials,
most efforts have been placed in the study of large deformation problems and there are …

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 …

The discrete-element method (DEM) has gained popularity for developing a qualitative
understanding of soil behaviour under a critical state soil mechanics (CSSM) framework …

Undrained and drained triaxial compression tests were simulated using the discrete element
method (DEM). It was found that the transition states between contractive and dilative …

The effects of particle shape (angularity α and sphericity S), physical properties (shear
modulus G p and Poisson's ratio ν p) and particle size distribution (uniformity coefficient C u) …

This technical note presents new experimental evidence for the role of grain shape in the
static liquefaction behaviour of sand–fines mixtures. The laboratory experiments comprise a …
