A dual-stage dimensionless method for simultaneous estimation of electrical conductivity, lift-off, and thickness in Eddy Current Testing

Puntos clave

• The method estimates electrical conductivity, lift-off, and thickness simultaneously.
• Improvement in measurement accuracy was noted, with errors reduced to 5.3% for thickness.
• Dual-stage dimensionless method provides a novel approach for electro-magnetic assessments.
• These findings indicate the method's potential for enhancing non-destructive testing practices.
