| Abstract: | Different resonant frequencies appeared in the determination experiment of dynamic Young modulus are theoretically analyzed based on the piezoelectric effect of piezoelectric ceramic crystal and the transverse vibration of both piezoelectric ceramic cudgel and the specimen. The theoretical analysis is consistent with the experimental results. |

| Keywords: | dynamic Young modulus resonant frequency piezoelectric effect transverse vibration |
