Modification of the granular fabric close to the surface changes the static angle of repose and the effect can still be noted after several inclinations of the cell indicating the existence of a memory effect.

Web1 de mai. de 2024 · Size-bidisperse granular mixtures with large size ratios flowing onto a quasi-2D bounded heap form stratified layers of large and small particles when the flow rate is modulated. These layers exhibit better average mixing than the segregated patterns generated by steady feed rates. WebThese angles are related to the internal friction of the material and its resistance to failure [7]. Critical angles have been extensively studied in previous studies [8–12] to characterize the stability of heaps of particles and most of the works were related to the characteristics and dynamics of avalanches [10,13–16].
