Description
1 microfiche (40 pages) : negative, illustrations; 11 x 15 cm.
Summary
"The application of ultrasound for the nondestructive evaluation of advanced composite materials is summarized. Quantitative indices from fundamental acoustic parameters of the inhomogeneous materials were derived. The investigations into the estimation of the average attenuation from backscattered ultrasound are described. The use of a centroid-shift technique in inhomogeneous materials is reported and investigation into the use of the Wigner distribution for attenuation estimation is summarized."--NTIS abstract.
