Identification of Stress Corrosion Cracking Profiles Using ε-Greedy Search Inverse Analysis in Eddy Current Testing

Abstract

This paper is concerned with a method to recover natural cracks from magnetic images obtained by ECT (eddy current testing). In the proposed method, a Database is built to store knowledge base of cracks with different sizes and various measurement parameters. In the proposed Inverse Analysis, ε-Greedy search algorithm invokes knowledge from pre-built database to reconstruct multiple cracks from ECT signals.
