Universal features of the stick-slip dynamics of an intruder moving through a confined granular medium
(2022-04-21)
Experiments and simulations of an intruder dragged by a spring through a two-dimensional annulus of granular
material exhibit robust force fluctuations. At low packing fractions (φ < φ0), the intruder clears an open ...
Determination of the angle of repose and coefficient of rolling friction for wood pellets
(2022-02-08)
The determination of the angle of repose for granular materials is indispensable for their handling and the design of containers and technological processing equipment. On the other hand, computational simulations have ...
