| Outline of Final Research Achievements |
S-version FEM code was updated. The crack closure effect is estimated by conventional method, and realistic fatigue crack growth simulation became possible. 3-dimensional crack growth simulation is applied to verify the alignment rule for nuclear power plant maintenance code. A new method estimating crack closure effect is proposed using AI technique. Basic research for the study by deep-learning is conducted. To improve the S-version FEM code, S-FEM seminars were organized. Research results have been published in the Journal and presented in domestic and international conferences
