Tip Location Determination of Exposed and Filled Cracks using Microwaves
Detection of exposed and filled fatigue/surface cracks on metal surfaces is an important practical issue. Recent approaches have shown the potential of detecting filled cracks and cracks covered with dielectric coatings. An important issue associated with these investigations is locating the tip of a crack. This is particularly important from a repair point of view. Open-ended rectangular waveguide probes are used to locate the tip of exposed and filled cracks. The results of several measurements will be discussed in this paper including the accuracy by which the tip may be located.
