Imperfections

Tips & Tricks

Stability analysis according to the second‑order theory requires imperfections to be applied.

The standards specify the relevant size and distributions which lead to efficient and reliable designs. RF‑/ FE‑LTB provides various setting for standardization of a mode shape. It is recommended to graphically check the imperfections applied in the calculation. You can display them in the Results Navigator.
