| Outline of Final Research Achievements |
Fracture on geological planes of weakness related to disasters like earthquakes whose mechanics is still unknown in many aspects has been considered. In particular, complex phenomena associated with three-dimensional fracture of planes of weakness have been dynamically studied using experimental, analytical as well as numerical methods. Based on the theoretical and experimental considerations, the influence of fracture complexities on the surroundings, natural and artificial structures has been evaluated. As a result, previously unrecognized facts such as generation of simple three-dimensional fracture patterns in brittle solids and two different ways of energy transmission in multi-dimensional granular media have been revealed.
