An expression for the angle of repose of dry cohesive granular materials on Earth and in planetary environments. [PDF]

Proc Natl Acad Sci U S A, 2021
Significance The angle between the sloping side of a heap of particles and the horizontal, called angle of repose, is often used to characterize the flowability of granular materials on Earth and planetary environments, such as sand, dust aerosols, and ...

Fundamental study on the effect of grain size distribution on angle of repose [PDF]

E3S Web of Conferences
In this study, the authors developed a new sidewall velocity-controlled cylindrical angle of repose measurement apparatus that can capture images of a sand heap continuously using two orthogonal cameras in order to reduce the cost of photography.

Microscopic Mechanism Angle of Repose in Friable Loess and Its Relationship With Slope Angle

Frontiers in Earth Science, 2022
The angle of repose in soil particles plays a key role in slope stability. There was a need for the investigation on the association between the angle of repose in loess particles and the angle of slopes.

Experimental Study of the Angle of Repose of Coral Sands

Journal of Marine Science and Engineering
The angle of repose is a fundamental parameter for assessing the stability of coral reefs. However, predictive models for this angle are currently lacking.

Angle of repose of granulated ice: effect of wood ash

Journal of Glaciology
New experiments have revealed that the addition of a small amount of wood ash doubles the angle of repose of granulated ice at −10°C, but has little effect at −30°C. It is hypothesized that this behavior may be explained in terms of the freezing of water

Angle of Repose and Angle of Marginal Stability: Molecular Dyanmics of Granular Particles [PDF]

Journal of Physics A: Mathematical and General, 1992
We present an implementation of realistic static friction in molecular dynamics (MD) simulations of granular particles. In our model, to break contacts between two particles, one has to apply a finite amount of force, determined by the Coulomb criterion.

Angle of repose and segregation in cohesive granular matter [PDF]

Physical Review E, 2001
We study the effect of fluids on the angle of repose and the segregation of granular matter poured into a silo. The experiments are conducted in two regimes where: (i) the volume fraction of the fluid is small and it forms liquid bridges between ...

Round robin test on angle of repose: DEM simulation results collected from 16 groups around the world

Soils and Foundations, 2023
The round robin test (the simultaneous analysis of the same problem) is a method to investigate the variance and sensitivity of results provided by different analysts for a given problem and the reliability of the particular software used by each group ...

ANALYSIS OF STATIC ANGLE OF REPOSE WITH RESPECT TO POWDER MATERIAL PROPERTIES

Acta Polytechnica, 2020
This paper investigates the Angle of Repose (AoR) of powder materials with respect to their morphological and rheological properties. Glass beads, sand, flour and semolina of different particle sizes were used as the experimental materials.
