Abstract

The ray arrival behavior of an ultrasonic signal propagated through a thick viscoelastic plate is analyzed to determine the material dispersion and attenuation. Signal processing algorithms are developed and demonstrated with synthetic and real signals obtained in elastic and viscoelastic materials. Recovery of material properties is found to proceed reliably except for the case of attenuation recovery from real signals, where there were difficulties related to the use of a finite aperture receiver.
