| Outline of Final Research Achievements |
Gel is a soft and elastic material made of polymer, and exhibits so called stick-slip motions when it is slid against a counter surface. Gel is sometimes used as an analogue material of earthquake faults due to similarity in its dynamical behavior. In this study, we conducted friction experiments using gels and found that the complexity and spatio-temporal heterogeneity in stick-slip motions can be well controlled by experimental parameters. In order to understand its local dynamics, we performed in-situ optical observations of frictional interfaces. As a result, we found some scaling relations connecting physical quantities that describe slip occurrence and experimental parameters.
