| Outline of Final Research Achievements |
Experimental studies were conducted to elucidate the physical properties of hierarchical granular matter, which is composed of macroscopic aggregates of microscopic particles. In particular, the physical responses of hierarchical granular matter to various disturbances such as impact, compression, vibration, and shearing were systematically investigated. As a result, the physical mechanisms of the effects of particles fracturing on the impact drag force produced by hierarchical granular matter, the oscillation in compressive force observed in the compressed hierarchical granular matter, the crack propagation in the vibrated fine granular columns, and the deformation of sand piles subjected to shear due to rotational centrifugal force were clarified. These results have significantly contributed to the elucidation of the physical properties of hierarchical granular matter.
