| Abstrakt: |
The wire specimens with artificial pits whose sizes were decided by the measured corrosion pit data. Three different pit shapes were assumed: round, triangle and triangle with a notch. Stress concentration factor at the sharp edge of pits were obtained by strain gauge measurement and 3D FEM analysis. Both methods showed that strain was almost same value and stress concentration is larger for sharper pit shapes. |
