Shear-wave propagation in rocks and other lossy media: An experimental study

Ultrasonic shear-wave propagation studies have been carried out for the measurements of velocity and attenuation in some rocks, concrete and synthetic materials at room conditions. It has been found that 'pulse broadening', which occurs due to attenuation, can be measured quite accurately while carrying out shearwave velocity measurements in them. The pulse broadening data could be used to determine the quality factor from which the shear-wave attenuation is computed using the standard relationships between velocity, attenuation and quality factor. The measurement technique is briefly described and the results obtained are presented and discussed.
