Abstract
An approximate method of calculating the signals from a defect for a s uperposed eddy-current transducer is described using the following mod el: The object being monitored has an extended defect in the form of a nonferromagnetic half-space with the eddy-current transducer situated symmetrically above it. Approximate calculations are presented with e xisting results. The approximate expressions obtained can be used as t he basis of an algorithm for calculating the depth of a defect.
