Yahya Choua was born in Kebdana, Morroco,in 1977. He received the Master degree in electrical engineering from the University Paris Sud XI, France in 2004, and the Ph.D. degree in physics in 2009 from the University Paris Sud XI. His research interests include electromagnetic modeling of probes in non destructive evaluation (NDE).

Thèse de doctorat soutenue le 1er octobre 2009 : Application de la méthode des éléments finis pour la modélisation de configurations de contrôle non destructif par courants de Foucault

Research activity

My research activity deals with the modeling of Eddy Current Testing (ECT) configurations. Usually this modeling cannot  be obtained analytically and requires the use of numerical methods. Among them, the finite element method (FEM) appears to be very powerful because of its large flexibility which allows to take into consideration complex configurations. However, if the FEM is appreciable for its flexibility, it can require preparation time (essentially the mesh) and of consequent calculation and involves an important qualification level of the operator. In this context, I studied various ways allowing to simplify the treatment by the FEM of an ECT problem. This work focuse mainly on the simplified modeling of a thin crack and on the mesh adaptation. They were established in two dual E and H formulations.
