Numerical Investigation on the Compressive Behavior of Hierarchical Granular Piles
Sota Arakawa, Mikito Furuichi, Daisuke Nishiura
Hierarchical granular piles composed of aggregates are key structural features in both geoscience and planetary science, from fault gouge in seismic zones to the internal structure…
On the elastoplastic behavior in collisional compression of spherical dust aggregates
Sota Arakawa, Hidekazu Tanaka, Eiichiro Kokubo +4
Aggregates consisting of submicron-sized cohesive dust grains are ubiquitous, and understanding the collisional behavior of dust aggregates is essential. It is known that low-speed…
Interparticle normal force in highly porous granular matter during compression
Sota Arakawa, Misako Tatsuuma, Hidekazu Tanaka +2
We perform a numerical simulation of compression of a highly porous dust aggregate of monodisperse spheres. We find that the average interparticle normal force within the aggregate…
Size Dependence of the Bouncing Barrier in Protoplanetary Dust Growth
Sota Arakawa, Satoshi Okuzumi, Misako Tatsuuma +5
Understanding the collisional behavior of dust aggregates is essential in the context of planet formation. It is known that low-velocity collisions of dust aggregates result in bou…
Interpebble contact radius in a comet nucleus
Sota Arakawa, Daisuke Nishiura, Mikito Furuichi
In recent years, the gravitational collapse of pebble clumps in the early Solar System has been regarded as a plausible scenario for the origin of comets. In this context, ``pebble…
Threshold velocity for collisional growth of porous dust aggregates consisting of cohesive frictionless spheres
Sota Arakawa, Hidekazu Tanaka, Eiichiro Kokubo +2
Understanding the collisional outcomes of dust aggregates and dependence on material properties of the constituting particles is of great importance toward understanding planet for…
