Amplified transport variability in granular slope flows near the critical angle
Fumiaki Nakai, Yuto Sasaki
Mechanical disturbances such as seismic shaking can set a granular slope in motion. Understanding the resulting transport before arrest is important for predicting topographic chan…
Granular Rods Fall Faster in Denser Obstacle Fields
Fumiaki Nakai, Hiroaki Katsuragi
How does particle shape affect driven transport through obstacle fields? We simulate a dissipative rod falling under gravity through randomly placed fixed obstacles. For sufficient…
Steady shear rheology of a granular crystal containing a single dislocation
Fumiaki Nakai
Monodisperse granular particles can form crystals whose yielding behavior is strongly affected by dislocations and differs markedly from that of conventional amorphous granular mat…
Anomalous phonon dispersion near yielding in athermal crystals
Fumiaki Nakai, Michio Otsuki, Kuniyasu Saitoh +1
Vibrational properties of ordered athermal solids near yielding remain poorly understood. We show that yielding in a sheared crystal is governed not by a single localized instabili…
