Application de la méthode des éléments finis pour la simulation 3D d’un dispositif de détection de défauts dans les matériaux conducteurs, Jul 20, 2017
Many techniques today allow non-destructive testing (NDT) or non-destructive evaluation (NDT) of ... more Many techniques today allow non-destructive testing (NDT) or non-destructive evaluation (NDT) of materials. The use of these techniques is particularly developed in the nuclear, gas, oil and aeronautical industries. They reveal the presence of defects, such as cracks, inclusions, corrosion, etc.
Among the most widely used methods is the technique of eddy current non-destructive testing (NDF-CF), the latter consists in evaluating the state of health of a part by measuring the variation of the impedance of inductive sensors.
This work synthesizes the study and simulation by the 3D finite element method of an eddy current fault detection device. The system is simulated under the Ansys-Maxwell environment, it has an air core coil placed over a conductive part representing a cracked support of a helicopter. In order to realize the crack detection, the coil scans the target and the signals are collected in terms of the variation of the impedance of the coil. The results obtained can constitute an important database for the opposite problem.
Key words: Nondestructive testing, cracks, eddy currents, 𝑇⃗ -ᴪ formulation, finite element method
