“…This model has been accepted as a. standard in fracture mechanics. Lecvkage field profile.^ liave been predicted by Lord and Hwang [43,44] and Satisli [4][5]46] by modeling Poisson"s equation in 2D. Lord, et al [47] took the process one step further and studied leakage field profiles for 3D pipeline structures.…”

This manuscript has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper aligimient 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 bad 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 corner and continuing from left to right in equal sections with small overlaps. 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. Higher 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.

“…Figure 1. a) shows a variable reluetanee (VR) probe whieh has been used to deteet magnetite buildup in the ereviee gap region between the ineoncl steam generator tubes and earbon steel support plates of a nuclear power plant steam generator unit [3). The bobbin-shaped probe earries ade excitation winding and the Hall plate measures the radial eomponent ofmagnetie flux density at one end of the soft iron bobbin.…”

“…As a specific example ofthe probe velocity effccts on the MFL output signal, a 'support plate signal' of a simple dc variable reluctance probe (Fig. 1), which has been used for steam generator tubing inspection [1,2,3], is studied. To suppress spurious oscillations, an upwinding technique is applied in the numerical analysis.…”
