Characterization of Surface Defects by Rayleigh-Waves
In this paper an approaching procedure will be demonstrated to determine the dimensions of cracklike surface defects by evaluating the amplitude of the reflected Rayleigh-wave signal as function of frequency. In order to treat the problem mathematically and experimentally the defect is modelled by a rectangular notch. The mathematical treatment as well as the experimental checking and last not least the determination of the crack parameters length, depth and width (see fig. 1) are presented.
