Description

Ultrasonic means have been used for the nondestructive evaluation (NDE) of a wide variety of mechanical properties in solid materials. Defects such as cracks and inclusions act as sources of wave scattering when illuminated by an incident pulse through reflection, diffraction and mode conversion. Interaction of elastic waves with cracks provides all the needed information relative to inverse characterization of the defects which has not been thoroughly solved yet. Fully understanding these interactions will provide more knowledge for implementing inverse algorithms.
