Abstract:
The high frequency, eddy current response from a wide variety of common metals shows a unique signature for each sample, reflecting the particular distribution of residual
stress in that sample. Individual samples are easily distinguished. A mathematical algorithm transforms the data gathered from the eddy current bridge into graphs that can
be used to identify stress as a function of depth. Metals measured include aluminum, steel, titanium and several nickel-based alloys. Specific experiments demonstrate that
the eddy current response is due to material stress and not other properties. Experiments in aluminum show the (reversible) effects of both tension and compression in
elastically deformed samples.
