This study evaluates stress corrosion cracks appearing in austenitic sta inless steel from the viewpoint of its resistance to eddy currents. Edd y current signals due to artificially introduced stress corrosion cracks are analyzed using finite element simulators to discuss its resistance . The results showed that the width and conductivity to model a stress corrosion crack vary significantly and furthermore depend on exciting f requency adopted. In contrast, however, the resistance of a crack, which is de...
