Three-dimensional sphericity, roundness and fractal dimension of sand particles (2018, background): “…the macroscopic mechanical properties of sands, such as their compressibility, shear strength, crushability and critical state behaviour, are highly influenced by the morphological features of the particles (Guo & Su, 2007; Rousé et al., 2008; Tsomokos & Georgiannou, 2010; Altuhafi & Coop, 2011).”
An investigation of single sand particle fracture using X-ray micro-tomography (2015, result): “Similar results have been reported by Altuhafi & Coop (2011) from one-dimensional compression on uniformly graded samples in which they used a 2D laser image analysis instrument to measure particle morphology after the tests.”
3D quantitative shape analysis on form, roundness, and compactness with μCT (2016, background): “smaller particles which are less spherical, less convex and with lower aspect ratio are generated when particles suffer catastrophic splitting [5].”
An approach to enhance efficiency of DEM modelling of soils with crushable grains (2015, background): “It has been repeatedly observed (e.g. Turcotte, 1986; McDowell et al., 1996; Altuhafi & Coop, 2011) that grain crushing leads to the emergence of a fractal distribution of particle sizes, with fractal dimension Æ close to 2.6.”
