Research Abstract

Granular materials can be regarded as continua, if macroscopic properties are concerned. On the other hand, discrete properties are essential near the boundary of the materials. The purpose of the present research is to establish a new physics that bridges the gap between the macroscopic and microscopic pictures. By the experiments using a vertically vibrated dry granular material, we have elucidated that the collective motions similar to the ones observed in elastic material or fluid can be generated if the number of layer (microscopic view) exceeds 3, but that their behaviors are characterized by the layer depth (macroscopic view). Moreover, the solid-like and fluid-like domains are found to co-exist and change to each other spatiotemporally to form wave motions. In the granular material exposed to viscous flows, we have shown that quite a small inhomogeneity of particle distribution can generate macroscopic landslides via rearrangement of particles and the flow concentration.
