Modelling of flawed riveted structures for EC inspection in aeronautics

Abstract : Within the framework of a collaborative project between CEA and EADS, a semi-analytical model based on a Volume Integral Method (VIM) has been developed so as to simulate the Eddy Current (EC) inspection of riveted structures in aeronautics. The modeling is the one of a layered planar structure with a flaw located nearby a fastener. The VIM involving dyadic Green's functions is considered, a fastener and a flaw being introduced as a variation of conductivity in a stack of slabs. This semi-analytical approach is compared to a Finite-Element one (FE) developed by LGEP and is validated with experimental data acquired on an aeronautical configuration.
