Frequencies and MAC coefficient for each modal shape for the damage scenario Case 5 (Lc = 500 mm, Hc/H = 10%). Identification of the most sensitive mode shape weighting of modal shapes in order to reduce those unwanted effects.
| Mode | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Undamaged frequencies [Hz] | 4.1311 | 25.8896 | 72.4918 | 142.055 | 234.827 | 350.791 |
| Damaged frequencies [Hz] | 4.12355 | 25.6877 | 72.4916 | 140.976 | 234.819 | 348.17 |
| Relative difference of frequencies [%] | 0.1846 | 0.77981 | 0.00025 | 0.75897 | 0.00320 | 0.746 |
| MAC coefficient | 0.99999 | 0.99993 | 0.99999 | 0.99958 | 0.99999 | 0.99881 |
