Surface Distributions for Eddy Current Probes

, 1986
This paper is concerned with the computation of the thin-skin solution for eddy current distributions induced in the presence of surface breaking flaws. Earlier work [1], [2], [3], [4] dealt with cases where the distribution induced in the absence of a flaw was uniform. An unfolding technique was developed which reduced the determination of the surface

Depth of penetration effects in eddy current testing [PDF]

, 2012
The simple depth of penetration equation used for most eddy current calculations does not take into account the effect of the size of the coil or the effect of flaw morphology. The work described in this paper describes use of the CIVA eddy current model

Evaluation of An Eddy-Current Tape-Head Probe

, 1984
SRI International is performing basic evaluation and characterization of eddy-current probes that are fabricated using ferrite tape-head technology. Tests conducted during the previous two years using both absolute and differential probes, frequencies of 100 kHz and 1 MHz, and flat-plate samples made of aluminum and titanium demonstrated that such ...
