Abstract
The purpose of this study is to examine the dynamic properties for viscoelastic materials over the wide range of frequency by measuring the change of waveform propagating in the bar. The viscoelastic properties in the frequency up to around 15 kHz can be evaluated by the impact test that the striker bar collides with the specimen bar mechanically. The properties of the high frequency area are different from those of the low frequency area. However, the impact tests using the striker bar cannot determine the dynamic characteristics in the high frequency range. The propagation tests using the wave packet generated by the ultrasonic transducers were performed. The attenuation and dispersion properties were examined by using the ultrasonic transducers having several characteristic frequencies within 25–200 kHz. It was found that the dynamic properties in the low frequency range could be identified as a three-element model based on the elementary theory. On the other hand, a five-element model based on the three-dimensional theory had to be applied in the high frequency range.
