This paper presents a review of the physics controlling various forces between clay particles,
and the incorporation of these forces in a DEM contact model in PFC 3D. This contact model …

Abstract A combined DEM-XFEM novel approach is used to simulate the direct shear test on
assemblies of breakable two-dimensional angular particles in order to study the macro-and …

This study investigates the relationship between clay minerals (kaolinite and illite) and rock
properties of the claystone, including both mechanical (cohesion, friction angle, stress, and …

This study presents an analysis of the association between the coefficient of permeability of
active clays and their porosity and tortuosity. Montmorillonite was selected because it is …

Tunnel face stability is critical for tunneling safety, especially in constructing a tunnel
adjacent to another. In tunnel construction, if there is an adjacent existing tunnel and the …

Soil strength is an influential property in determining agricultural and geotechnical
outcomes. In uniaxial compression test the strength of artificial aggregates containing …

In this study, a series of dynamic triaxial tests and corresponding simulations using discrete
element method (DEM) were conducted on sand with different clay particle contents. The …

The importance and quality of particle orientation on the performance of clay has been well-
documented experimentally. This paper aims to quantitatively evaluate clayey mineral …

The current study examined the creep behavior of clay in terms of particle sliding using
samples containing montmorillonite and kaolinite by modeling all interparticle forces using …

The aim of this study is to simplify the incorporation of the physico-chemical forces between
clay particles in discrete element method (DEM) simulations to reduce the computational …
