| Outline of Final Research Achievements |
Physical processes of fracture of planes of weakness, especially the details of their dynamics, have been studied by combining analytical and numerical methods as well as dynamic fracture experiments. Also, quantitative aspects of natural disasters and structural failures that may be induced by fracture of planes of weakness have been evaluated. By introducing also an applied mechanics-based approach, as a result, possible physical ground behind the difference between the observed dip-slip seismic motion on the hanging wall and that on the footwall has been analytically and experimentally shown.
