TL;DR: A new scheme for the fast evaluation of eddy current testing (ECT) signals by using databases and formulation of the A−φ method that can predict ECT signals due to a large and complex-shaped crack rapidly because of its higher order interpolation and the newly introduced special element, say, an element with different media.

TL;DR: The first EAST upper W/Cu divertor was completed in the spring of 2014, consisting of 80 cassette bodies toroidally assembled as mentioned in this paper, with heat removal capability up to 10 MW m−2.

TL;DR: In this article, an inversion algorithm for three-dimensional profile reconstruction of wall thinning defect in a double-layer region of a typical coolant pipe of nuclear power plants from pulsed eddy current testing (PECT) signals has been proposed and experimentally validated, based on a fast simulator of PECT signals and a deterministic optimization strategy.

TL;DR: A comparison of numerical results of the two proposed simulation methods and experimental results indicates that both of these simulation methods can model PECT signals with high precision, but the frequency domain summation method combined with an interpolation strategy is much more efficient in its use of simulation time.

TL;DR: In the future, for magnetic memory method, it is necessary to strengthen the microscopic observations of magnetic domains, experiments of magnetomechanical constitutive, establishment of quantitative models, modeling of complex influencing factors, and the study of identification, inversion and criteria.
