Abstract (EN): The present study evaluates the applicability of the SPATE system to the detection of hidden cracks in plates of aluminium ahoy 2024-T3 alclad 1.6 mm thick, taken from riveted lap-joints. Artificial part-through cracks were used to simulate a hidden crack in one face, and SPATE readings were performed on the opposite face. The results show that the SPATE system can detect a hidden part-through crack with a minimum depth of 0.6 mm. Finite element modelling indicates a large stress gradient in the vicinity of the crack. Due to Limitations of the SPATE discussed in the paper, that gradient could not be experimentally measured.
