Abstract :
The use of an open-ended waveguide probe for detection and sizing of fatigue cracks in metals is explained. The fatigue crack is assumed to be a surface-breaking crack with elliptical shape. The signals associated with elliptical cracks are examined and techniques for inverting crack signals to crack dimensions are outlined.
