Wave Dispersion and Attenuation in Viscoelastic Split Hopkinson Pressure Bar

Wave Dispersion and Attenuation in Viscoelastic Split Hopkinson Pressure Bar

A viscoelastic split Hopkinson pressure bar intended for testing soft materials with low acoustic impedance is studied. Using one-dimensional linear viscoelastic wave propagation theory, the basic equations have been established for the determination of the stress—strain—strain rate relationship for...
