| Outline of Final Research Achievements |
This study discussed the investigation of fatigue properties under non-proportional multiaxial random loadings to improve safety design and reliable maintenance for structure components and materials based on a series of the delegate’s works. Developments of damage model and design tool to evaluate state of stress and strain multiaxiality as well as damage under the loadings are also carried out.
