This manuscript addresses the problem of evaluating the “classical” problem of estimating electrical conductivity of metals. The novel contribution of this work is the use of time constants of the source-free response in a pulsed eddy current testing (PECT) experiment. Time constants characterize the source-free response and increase monotonically with the electrical conductivity of the specimen. Source-free time constants are particularly important set of features because they do not depend upon the probing system and hence they are not sensitive to probe lift-off and tilts that are responsible for significant experimental errors.

Abstract
This manuscript addresses the problem of evaluating the “classical” problem of estimating electrical conductivity of metals. The novel contribution of this work is the use of time constants of the source-free response in a pulsed eddy current testing (PECT) experiment. Time constants characterize the source-free response and increase monotonically with the electrical conductivity of the specimen. Source-free time constants are particularly important set of features because they do not depend upon the probing system and hence they are not sensitive to probe lift-off and tilts that are responsible for significant experimental errors.File in questo prodotto:
