Figure 1.

Normalized eigenfrequencies $\hat{\omega }$ of a clamped-free gyro-elastic beam for different values of the normalized gyricity constant $\hat{h}$. In the diagram, the square roots of $\hat{\omega }$ and $\hat{h}$ are plotted. Some of the eigenmodes are shown in the insets, where the small crosses indicate the positions of the inflection points.
