International audienceOne of the Eddy Current (EC) testing issues in aeronautics is the inspection of fastened structures to detect flaws nearby rivets which can grow because of mechanical stress. EADS and the CEA LIST have started a collaborative work with the support of the Île-de-France Region to develop a simulation tool of EC fastened structures testing, integrated to the CIVA platform, aimed at conceiving testing methods, optimizing and qualifying it. The volume integral method using a multilayer Green dyadic formalism has been chosen in order to get a fast resolution of Maxwell equations. The flaw response simulation mostly has to cope with a scale issue between the size of the rivet and the one of the flaw. The whole model has been ...
