Abstract:The demand for recycled metals is growing exponentially, making it imperative for in dustries to adapt to sustainable practices. However, the use of recycled metals can pose challenges due to their unpredictable behavior. To address this, significant efforts have been made in the field of Eddy Current testing to monitor the material properties of recycled metals. Nonetheless, interpreting Eddy Current sensor signals to estimate the mechanical properties remains a challenge. Previous studies have focused on individual aspects of Eddy Current testing, such as magnetic homogenization or coil winding modeling, without providing a comprehensive framework to relate the sensor signal to the mechanical properties of the sheet. The primary objective of this thesis is to present a modeling framework that relates the Eddy Current sensor signal to the mechanical properties of the sheet. Achieving this objective entails a detailed study of inductance calculations and Eddy Current sensor modeling. The models developed in this study are validated with experiments and used to describe the relationship between the sensor signal and the magnetic properties of the sheet. In addition, the study employs mechanical and magnetic homogenization techniques to investigate the relationship between the magnetic and mechanical properties of AISI420.
