“…It constitutes a significant limitation, especially in diagnosing complex geometry elements and multilayer ones [ 7 ]. On the other hand, the development of numerical simulation methods allows for creating models that make it possible to determine the distribution of electromagnetic fields and to calculate eddy current characteristics, which may, in turn, make an additional reference to improve the diagnostic process [ 7 , 8 ].…”

In this paper, a novel approach to Non-Destructive Testing (NDT) of defective materials for the aircraft industry is proposed, which utilizes an approach based on multifrequency and spectrogram eddy current method combined with an image analysis method previously applied for general-purpose full-reference image quality assessment (FR IQA). The proposed defect identification method is based on the use of the modified SSIM4 image quality metric. The developed method was thoroughly tested for various locations, sizes, and configurations of defects in the examined structure. Its application makes it possible to not only determine the presence of cracks but also estimate their size.

“…In this chapter we apply a wavelet expansion to the volume integral method to reduce the computational complexity of the method. Part of the content in this chapter has been presented in Reference [39] and [40]. Results from the wavelet method have been compared with results from a layer approximation and experimental results [12].…”

This manuscript has been reproduced from the microfihn master. UMI fihns the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter &ce, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quali^ of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overiaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Ifigher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

“…Second, experimental measurements are relatively straightforward. Third, a numerically-exact volume element method has recently been developed to treat defects in this plate geometry [ 14]. Fourth, the sample simulates pitting corrosion on the hidden side of a plate and is of great industrial utility.…”

“…The resulting matrix is too large for storage. Consequently, a novel Wavelet basis was used [14], which has the effect of concentrating the elements where the field is rapidly varying and thus reducing the size of the resulting matrix.…”
