The macroscopic response of a geomaterial is entirely determined by changes at the particle
scale. It has been established that particle crushing is affected by particle size, shape and …

The breakage behaviour of a pre-crushed carbonate sand sheared within a miniature triaxial
loading apparatus is investigated using high-spatial resolution X-ray micro-tomography. Full …

This work uses synchrotron X-ray tomography to quantify the role of the particle shape on
the interaction between collective comminution and individual grain fracture. Two sands …

This paper presents the results and analyses of uniaxial compression experiments
performed on three silica sands. The sands have comparable particle-size distributions, but …

The objective of our research is to define a new Discrete Element Method (DEM) that can
describe the processes involved in particle breakage and the resulting macroscopic …

This paper presents an improved region growing method for the segmentation of images
comprising three phases. It is shown that image segmentation errors usually occur at the …

Grain breakage affects a number of geotechnical engineering problems. In this research
study, the breakage of an artificial, porous granular material (light-expanded clay aggregate …

X-ray μ CT imaging is a common technique that is used to gain access to the full-field
characterization of materials. Nevertheless, the process can be expensive and time …

Deformation experiments with concurrent X-ray microtomography are used to characterize
the mechanical properties of a high-porosity carbonate rock from Central Europe (the …

The majority of constitutive models, that are used nowadays to describe the behaviour of
granular materials such as sands, are continuum models based on phenomenological …
