Eddy current testing of ferromagnetic materials: modelling of multiple flows in a planar stratified medium

International audienceFollowing a previous work carried out at the laboratory in the case of one flaw located in a cylindrical ferromagnetic piece, the development presented herein address the case of multiple interacting flaws located inside a planar, stratified and ferromagnetic medium. Simulation results are obtained through the application of the Volume Integral Method (VIM)
