| Outline of Final Research Achievements |
The evaluation of the microscopic stress or strain distribution at crystalline scale is essential in the investigation of the deformation and fracture behavior of structural metallic materials. In this study, the following two approaches were taken: (1) Measurement of displacement and strain on the specimen surface by digital image correlation (DIC) technique, (2) Numerical simulation of microscopic stress and strain distribution considering crystal anisotropy and crystal plasticity. Additionally, a method to determine slip deformation at crystalline scale that can reproduce the measured deformation obtained by DIC approach on the specimen surface was proposed. Microscopic stress distribution was estimated based on the determined slip deformation considering crystalline orientation.
