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)…

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…
