Determination of the useful frequency for the calculation of the attenuation coefficient and phase velocity in a viscoelastic Hopkinson Pressure bar

The propagation coefficient associated with the wave dispersion and attenuation in viscoelastic bars is calculated experimentally. The phase velocity and the attenuation coefficient in relation to the frequency are obtained from a series of impact tests on a PMMA Hopkinson pressure bar using ball be...
