Full text[This contribution describes a pulsed eddy current test equipment developed for defect detection in metallic materials and especially in austenitic steels. Two simplified models are used to describe the electromagnetic phenomena during control The exciting and receiving circuits,- as well as the probe coil arrangements, optimized to increase the depth detection limit or the transverse resolution power, are presented. Signal processing and analysis methods, adapted to pulsed eddy currents have been developed to detect the defect and characterize its depth. Applications to thickness measurements and defect detection are also outlined. ]

Full textThis thesis is about Non Destructive Testing by eddy currents. The goal is to develop new methods to compute the impedance variation of emitting coil placed over a conductive plate, possibly containing cracks. Standard methods require volume finite element meshes. This usually implies a computation cost and data storage high. In this thesis, we consider a solution to the problem by choosing to see is as a transmission problem on the interface between the conducting plate and the air containing the coil. When the conductor has no crack, we develop an approximate method to compute the impedance variation of a coil placed on the conductive plate. Applying this method only requires inverting sparse linear systems, this reduces the computation cost and the data storage requirements. If the plate containing a crack, the crack modeled as fictive current charge. After formulating the problem this way, the difficult part is to compute the fictive charge. We offer a method to compute it when the conducting plate has a high conductivity. It is based on asymptotic developments for high wave numbers

Full textThe non destructive eddy current testing is widely used in inspection of conductive materials. The use of arrayed sensors assures the control of wide surfaces and reduces the measurement noise due to the sensor displacement. On the other hand, the miniaturisation of sensors gives a best spatial resolution. In the case of sampled functioning, the modelling techniques are the same as those used for a single sensor. However, the simultaneous functioning of the sensors, while reducing the time response, requires the implementation of new modelling techniques. In this thesis, the models of single sensor system are exploited in the aim to be generalized for the case of arrayed configuration. The principle of superposition is applied to the results obtained for a single sensor system using the 2D finite element method. The 3D distribution of the electromagnetic source field is then rapidly reconstituted. A perturbation method is used in order to calculate the reaction field. This technique, when reducing the 3D computation domain to the region neighbouring the defect, brings a gain in time computing and space memory. With the aim of getting a fast direct model adapted to the iterative inversion, the ideal crack model based on the dyadic Green’s functions is generalized to the case of arrayed sensors. Finally, an inversion method using genetic algorithms is applied to reconstitute the defect geometry. The proposed models are then validated via 3D finite element computation and experimental measurements
