Analytical solutions to the diffraction of elastic waves by elliptical cracks in titanium are compared with experimental results. The analysis is based on physical elastodynamic theory and is valid for ka≫1 and in the far field. A digitized ultrasonic spectrum analysis system is used to measure the frequency components of broadband waves diffracted from elliptical cracks with aspect ratios (ratio of major to minor axes) ranging from 1 to 8. The amplitude spectra show good agreement between experiment and theory.
