3MA finite element modeling of 3MA NDT devices in different inspection situation

Currently, the nondestructive characterization of materials with electromagnetic NDT methods requires a huge amount of experiments and establishments of complex formulas to recover the magnetic and mechanical behavior of the material. All these measurements are very costly in terms of money and time, which is why the use of such NDT techniques often remains limited today. In order to speed up the characterization process, analytical and numerical simulations are run in order to predict the a priori magnetic behavior of the material in different inspection situations and to reduce the measurement series. Therefore, Fraunhofer IZFP has focused his efforts to develop an electromagnetic FEM tool using Flux Software (developed by CEDRAT) which is able to reproduce the Inspection Situation with 3MA device and to simulate the magnetic signatures.
