Characterization of viscoelastic properties of polymer bar using iterative deconvolution in the time domain

A new approach to characterize the viscoelastic properties of a polymer bar using wave propagation phenomenon that is dominated by attenuation and dispersion is presented. A novel iterative deconvolution algorithm is proposed to directly extract the impulse response function (IRF) from the measured...
