Energy dissipation of a sphere rolling up a granular slope: slip and deformation of granular surface
Takeshi Fukumoto, Ken Yamamoto, Makoto Katsura +1
We experimentally investigate the dynamics of a sphere rolling up a granular slope. During the rolling-up motion, the sphere experiences slipping and penetration (groove formation)…
Fracturing-induced fluidization of vibrated fine-powder column
Prasad Sonar, Hiroaki Katsuragi
We experimentally investigate the effect of vertical vibrations on the brittle behavior of fine cohesive powders consisting of glass beads of 5 microns in diameter. This is an atte…
Decompaction-wave propagation in a vibrated fine powder bed
Prasad Sonar, Hiroaki Katsuragi
We experimentally study the crack formation and decompaction-wave propagating in a vibrated powder bed consisting of glass beads of 5 μm in diameter. The vibrated powder bed exhibi…
History-dependent growth and reduction of the ripples formed on a swept granular track
S. Hata, M. Katsura, H. Katsuragi
When a solid object or wheel is repeatedly dragged on a dry sandy surface, ripple patterns are formed. Although the conditions to form ripple patterns have been studied well, metho…
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…
Grain size effect on the compression and relaxation of a granular column: solid particles vs dust agglomerates
Felipe Pacheco-Vázquez, Tomomi Omura, Hiroaki Katsuragi
We studied experimentally the effect of grain size and maximum load on the compaction and subsequent relaxation of a granular column when it is subjected to vertical uniaxial compr…
