Discussion of “Influence of Particle Size and Gradation on the Stress-Dilatancy Behavior of Granular Materials during Drained Triaxial Compression” by Samaneh Amirpour Harehdasht, Mourad Karray, Mahmoud N. Hussien, and Mohamed Chekired

Particle Sorting in Scree Slopes: Characterization and Interpretation From the Micromechanical Perspective

“…The basic particle attributes play a critical role in the mechanical behavior of granular materials (Cavarretta et al., 2010; Yang & Wei, 2012; Dai et al., 2016; Dai, 2018a) (Table 1). We used five granular materials (i.e., glass bead, dolomite rock grain, cobble, sandstone, and basalt rock grain) to study the effect of particle size and shape on the characteristics of accumulated granular mass (see Figures 2b–2f).…”
