The main methods, listed below, are for the most part constantly evolving to respond to increasingly rapid market developments and the development of new materials Looking for a job in the field of NDT?

Surface integral formulation of Maxwell’s equations for simulation of non-destructive testing by eddy currents.

To do foucalut, simply fill out our form and specify your request, sector and theme. Employee wishing to specialize in a particular test method? The numerical results obtained using this formulation involve plates with consideration of edge effects such as edge and corner.

A foucajlt attention has been given to the choice of basis functions which have to satisfy an Hdiv conforming property and on the evaluation of near interactions which are weakly singular. However, it was not until the Second World War that these developments in the transmitting and receiving of electromagnetic waves were put to practical use for materials testing.


Preliminary study on the implementation of the fast multipole method. Cela nous a permis de traiter plusieurs seconds membres ie. Monday, March 21, – 5: There have been many recent developments in eddy current testing, leading to improved performance and the development of new applications.

We were thus brought to formulate the electromagnetic problem differently, by setting ourselves the goal of maintaining a semi-analytical approach.

Tekoing Lim 1 AuthorId: Find all the information you need to find a training, an internship or a job in the field of NDT. This problem is approached by a linear system by the method of momentswhose number of unknowns is reduced due to the nature of the surfacic mesh. Foucault built a device that used a copper disk moving in a strong magnetic field to show that eddy currents magnetic fields are generated when a material moves within an applied magnetic field.

As a representative of the profession, COFREND is also a partner with other associations and professional organizations, both nationally and internationally. For larger configurations, we conducted a preliminary study for the adaptation of an acceleration method of the matrix-vector product involved in an iterative solver fast multipole method or FMM to define the conditions under which the FMM calculation works correctly accuracy, convergence To simulate numerically a non-destructive by eddy current testing NDT-CFthe sensor response can be modeled through a semi-analytical approach by volume integral equations.

Ecole Polytechnique X, They are consistent with results obtained by the finite element method. Menu More Pour nous joindre. Faster than the finite element method, this approach is however restricted to the study of plane or cylindrical parts without taking into account the edge effects because of the complexity of the expression of the dyadic Green function for more general configurations.


Faraday discovered that foucailt a magnetic field passes through a conductor a material in which electrons move easily -or when a conductor passes through a magnetic field-an electric current will flow through the conductor if there is a closed path through which the current can circulate.

Tekoing Lim 1 Details. Friday, November 9, – Many advances were made throughout the s and s, especially in the aircraft and nuclear industries.

That enabled us to treat several various positions of the sensor for only one inversion of the impedance matrix. The surface integral equation SIE expresses the volume problem by an equivalent transmission one at the interfaces 2D between homogeneous subdomains. Other companies soon followed.
