Abstract: The authors consider the detection of cracks appearing close to the rivets in ageing riveted lap joints of aircraft structures, using the eddy current (EC) technique. As the presence of the rivets perturbs the interpretability of the defect EC signatures, the authors propose to fuse the data provided by oriented field EC sensors used in different operating modes. Different fusion rules are considered and the performances of defect detection are then characterized with receiver operating characteristic curves.

Keywords: EC sensor, defect detection, riveted lap joints, data fusion, receiver operating characteristic
