Abstract
A method for evaluating the wall thickness of a hollow part, of the turbomachine blade type, at least at a point having a determined radius of curvature at this point, within determined ranges of radii of curvature and thicknesses, including the determination of impedance values of an electrical circuit formed by an eddy current detector applied to the wall, and the insertion of these values into a digital processing unit with a neural network, wherein the network parameters have been defined in advance by learning on spacers having a determined radius of curvature and thickness in the ranges.
