| Outline of Final Research Achievements |
Micro characterization such as grain movement or strain localization in sandy soil is investigated using micro X-ray tomography. Moreover, failure of soil under seepage flow is visualized and evaluated in 3D using tomography images.
Finite element (FE) modeling of sand with microcharacterization is discussed in this research. The proposed FE method is implemented with particle discretization whose mesh size and geometry is determined from X-ray CT data. In this study, a series of results of triaxial compression tests on sand are discussed. Laboratory test results are compared with simulation results, and the validation of the proposed model is discussed.
