Microbially induced calcium carbonate precipitation (MICP) has attracted much attention as
a promising green technique for soil improvement. Despite the significance of precipitation …

Accurate prediction of fracture in concrete depends on the characterization of real meso-
structures. Micro X-ray computed tomography (CT) can fulfil this task but is still too expensive …

The physical and mechanical performance of concrete is inherently dependent on
aggregate morphology including the general shape at coarse-scale, the local roundness at …

The effects of multi-scale particle shape characteristics on the small-strain stiffness of
granular soils remain controversial. This study revisits this topic using well-calibrated three …

This paper presents a numerical investigation about the effect of particle shape on small
strain properties (eg, shear stiffness and Poisson's ratio) of granular soils through 3D …

The multi-scale characteristics of particle morphology, including the overall form, local
roundness and surface roughness, affect the critical state behavior of sands and should be …

The collapse of natural granular particles is encountered in various scenarios, including
landslides, tsunamis, avalanches, and industrial processes. However, our understanding of …

To explore the fractal dimension, particle shape, and particle breakage of calcareous sand
(CS) under multi-level ending pressure, a series of one-dimensional compression …

This paper adopts a micro-tomography (μCT)-based discrete element method (DEM)
technique to generate a database for the constitutive modelling of granular soils. A large …

Inherent fabrics exist in natural soils during deposition. After applying stresses, inherent
fabrics in soils are altered due to the rearrangement of soil particles, which gives rise to …
