... was used to curve fit the stress-relaxation data, while the dynamic data were used both to determine the dynamic properties through fast Fourier transform analysis and to validate the dynamic behavior based on the properties obtained from the QLV theory. Comparisons of the curve-fit parameters showed...

.... The phase velocity of the samples using the new method had significantly high correlation to the bulk stiffness of the samples ( r = 0.84 ) compared to the phase velocity measured using fast Fourier transform FFT ( r = 0.14 ) . In conclusion, the new method provided an accurate measurement of the ultrasound...
