• Effect of particle shape and validity of Gmax models for sand: A critical review and a new expression (2016, background): “On the other hand, as has been shown by a number of investigators, particle shape can have a significant influence on the small-strain shear modulus of sands [2,34,24,22].”
• Rheological and mechanical properties of mortars prepared with natural and manufactured sands (2008, background): “Rough angular particles yield a granular packing of lower density, lower small strain stiffness, and higher critical state friction angle when compared with more rounded natural sands [ 1 ].”
• A novel three-dimensional contact model for granulates incorporating rolling and twisting resistances (2015, methodology): “C 2k is plotted instead of k as it has a better correlation with 1 q, as reported in [2].”
• 3D quantitative shape analysis on form, roundness, and compactness with μCT (2016, background): “…Technology j ourna l homepage: www.e lsev ie r .com/ locate /powtec 3D quantitative shape analysis on form, roundness, and compactness with μCT Budi Zhao, Jianfeng Wang ⁎ Department of Architecture and Civil Engineering, City University of Hong Kong, Hong Kong, China ⁎ Corresponding author.”
• Level set discrete element method for three-dimensional computations with triaxial case study (2016, background): “Particle shape plays an enormous role in determining the macroscopic properties of an assembly, particularly strength, which has been shown both experimentally (Cho et al., 2006) and computationally (Andrade et al., 2012), so having a method able to account for particle shape is paramount.”
• Effects of particle asphericity on the macro- and micro-mechanical behaviors of granular assemblies (2017, neutral): “, Ottawa 20–30 sands [40] popularly used in geotechnical tests.”
• An investigation of single sand particle fracture using X-ray micro-tomography (2015, background): “The shape of a particle can be decomposed into components in three scales, sphericity (or form), roundness (or angularity) and roughness (or smoothness) (Barrett, 1980; Cho et al., 2006).”
• The influence of particle characteristics on the behaviour of coarse grained soils (2010, methodology): “Regularity, r, is the mean of s and r; use of this single parameter to relate shape and mechanical properties was proposed by Cho et al. (2006).”
• Exploring the relationship between critical state and particle shape for granular materials (2015, methodology): “…soils, resulting in valuable data and insights that contribute to an improved understanding in several aspects (e.g., Sukumaran and Ashmawy, 2001; Cho et al., 2006; Rouse et al., 2008; Wichtmann and Triantafyllidis, 2009; Cavarretta et al., 2010; Yang and Wei, 2012; and the references therein).”
• Discrete-element method analysis of the state parameter (2014, methodology): “Although the Mcs value obtained in the current DEM simulations is much smaller than that of real Toyoura sand (Mcs 1.24) (Cho et al., 2006), it is close to the Mcs value of glass beads (Mcs 0.82) (Cavarretta, 2009).”
• Dependence of shape on particle size for a crushed rock railway ballast (2013, background): “[4] explored the impact of particle shape on sandy soils by comparing data from published studies; they too considered relatively large changes in shape to identify a number of trends in soil behavior.”
• Shear stiffness of granular material at small strains: does it depend on grain size? (2013, background): “Their simple and spherical geometry, together with the same uniformity, allowed the influences of particle shape (Cho et al., 2006) and particle size distribution (Wichtmann & Triantafyllidis, 2009) to be isolated, so that any observed difference is attributable to the difference in particle size.”
