Evaluation of Small Defects by Wavelet Analysis of Scattering Ultrasonic

Nondestructive evaluation method of the density and mean diameter of small defects in the material using wavelet analysis of scattering ultrasonic waves was developed. The relationship between scattering ultrasonic frequancy characteristics (noise energy and center of the frequency) and defects char...
