Constitutive flow law for hydrogel granular rafts near the brittle-ductile transition
Yuto Sasaki, Hiroaki Katsuragi
Spatially varying flow laws have been identified in dry granular flow, yet their applicability to unjammed suspensions remains unclear. This study demonstrates that the quasistatic…
Origin of slow earthquake statistics in low-friction soft granular shear
Yuto Sasaki, Hiroaki Katsuragi
Slow earthquakes differ from regular earthquakes in their slower moment release and size distribution dominated by smaller events. However, the physical origin of these slow earthq…
Dislocation Glides in Monolayered Granular Media: Effect of Lattice Constant
Fumiaki Nakai, Takashi Uneyama, Yuto Sasaki +2
A recent study demonstrated that granular crystals containing a single dislocation exhibit dislocation glide analogous to that observed in atomic-scale crystals, resulting in plast…
Dislocation Glides in Granular Media
Fumiaki Nakai, Takashi Uneyama, Yuto Sasaki +2
Atomic crystals with dislocations deform plastically at low stresses via dislocation glide. Whether dislocation glide occurs in macroscopic frictional granular media has remained u…
