Method for imaging corrosion damage in thin plates from electrostatic data

. The problem of quantitative nondestructive evaluation of corrosion in plates is considered. The inpection method uses boundary measurements of currents and voltages to determine the material loss caused by corrosion. The development of the method is based on linearization and the assumption that the plate is thin. The behavior of the method is examined in numerical simulations. Key words. nondestructive evaluation, corrosion monitoring, electrical impedance tomography, numerical reconstruction methods 1 Research partially supported by an NSF Mathematical Sciences Graduate Fellowship and by the Department of Energy under grant DE-FG02-94ER25225. 2 Research partially supported by the Air Force Office of Scientific Research under a URI-RIP grant F4962093 -I-0500, the Department of Energy under grant DE-FG02-94ER25225, the National Science Foundation under grant DMS-9210489, and in part by the Cornell Theory Center which receives major funding from the National Science Foundation and...
