Deformation of a rotated granular pile governed by body-force-dependent friction
T. Irie, R. Yamaguchi, S. Watanabe +1
Although the gravity dependence of granular friction is crucial to understand various natural phenomena, its precise characterization is difficult. We propose a method to character…
History-dependent deformation of a rotated granular pile governed by granular friction
T. Irie, R. Yamaguchi, S. Watanabe +1
We experimentally examined the history dependence of the rotation-induced granular deformation. As an initial state, we prepared a quasi-two-dimensional granular pile whose apex is…
Measurement of surface deformation and cohesion of a granular pile under the effect of centrifugal force
T. i Irie, R. Yamaguchi, S. Watanabe +1
An experimental apparatus measuring free-surface deformation of a centrifuged granular pile is developed. By horizontally rotating a quasi two-dimensional granular pile whose apex…
SPH Simulations for Shape Deformation of Rubble-Pile Asteroids Through Spinup: The Challenge for Making Top-Shaped Asteroids Ryugu and Bennu
Keisuke Sugiura, Hiroshi Kobayashi, Sei-ichiro Watanabe +3
Asteroid Ryugu and asteroid Bennu, which were recently visited by spacecraft Hayabusa2 and OSIRIS-REx, respectively, are spinning top-shaped rubble piles. Other axisymmetric top-sh…
