Hyperbolic Model Based Data Evaluation for Magnetic NDE Measurements
In this paper a new data evaluation technique is presented for non-destructive magnetic measurements. This method is based on the multiphase hyperbolic model of magnetization and it is called model based data evaluation (MBDE) technique. The MBDE method allows us to separate the magnetic contribution of the magnetizing yoke from the measured magnetization curves. Therefore the determined magnetic properties of the tested sample are independent of the parameters of the applied magnetic yoke and the lift-off. The proposed method could become a useful tool in magnetic non-destructive evaluation (NDE).
