Abstract :
Eddy current techniques (ECTs) for nondestructive testing and evaluation (NDT/NDE) of conducting materials is one of most application-oriented field of research within electromagnetics. In this work, quantitative nondestructive evaluation of corrosion in metallic plates is considered. The inspection method exploits impedance measurements to determine the material loss profile caused by corrosion. Considering the corrosion shape as an impedance measurements´ function, it has to be minimized in order to obtain the corrosion profile. Particularly, swarm intelligence, characterized by evolutionary computation, has been exploited for the purpose
