| Abstract: | The frequencies and displacement node positions are measured under the boundaries of free-free ends for the ultrasonic flexural vibrations of exponential bars with constant thickness and rectangular cross section. The comparison of experimental results with theories testifies the correctness of Timoshenko's theory Finally, the measurements and the analysis are made of the harmonic frequencies of wedge bars and of the corresponding exponential bars in flexural vibrations. |

| Keywords: | Timoshenko's theory constant thickness flexural vibrations non-uniform cross section |
