| Outline of Final Research Achievements |
Jamming is observed in dense particle assemblies, such as granular materials, colloidal suspensions, foams. To understand the rheological behavior of materials near the transition point, we investigate the various systems related with the jamming transition. For elastic behaviors of jammed materials, we have found critical scaling laws describing the shear modulus near the transition point. We also proposed a theory on the friction law of elastomer, which predict the decrease of the friction coefficient with increasing pressure. The theory is confirmed by experiments.
