Abstract

With a view to improving the efficiency of flaw detection based on various geometric parameters and aimed at cracks of various configurations, we suggest a modified version of the Fibonacci strategy for fast detection of maximal amplitudes of pulse envelopes from an eddy-current transducer (ECT) scanning the surface of a tested object. The suggested algorithm prescribes a unified procedure in the cases of the unimodal, bimodal, and local-bimodal shapes of ECT pulse envelopes and allows a considerable reduction in the number of steps in the search process.
