Abstract :
In the ideal crack model in eddy-current testing frame, the field-flaw is equivalent to a current dipole layer on its surface. This model has shown its efficiency, as well for the computing accuracy, as for the CPU time. The goal of this paper is to improve this model taking into account the inclination, the conductance, and the low thickness of the crack.
