Eddy-current modeling of ferrite-cored probes
Résumé
CEA has developed a fast code for the simulation of eddy-current probes. It is based on the Volume Integral (VIM) approach. Within the framework of an EADS partnership, this code has been extended to the simulation of different kinds of ferrite-cored probes with for example I, C or E shapes. The model gives the response of the probe to a parallelepiped 3D flaw included in a conductive slab. It has been benchmarked with experimental data for several configurations and an excellent agreement has been achieved.
