| Outline of Final Research Achievements |
Generally, metallic materials consist of multiple phase, and consequently, various properties are inhomogeneous. In this study, a numerical simulation model to calculate the microscopic distribution of stress and diffusible hydrogen concentration was proposed. The simulation method was applied to calculate the inhomogeneous distribution of the stress and diffusible hydrogen distribution at microscopic scale in the hydrogen cracking test. The characteristics of the distribution was in good agreement with the tendency of the observed cracks in the experiment. The approach is applicable to the evaluation of hydrogen cracking behavior of materials with multiple microstructure.
