Abstract
A method of magnetic crack depth prediction for a magnetisable component of a first geometry comprising determining a measure of remnant magnetic flux leakage for a section of the component and, converting the remnant magnetic flux leakage to a predicted crack depth for that section of the component using an empirically determined relationship between remnant magnetic flux leakage and crack depth for a previously tested in service component of the first geometry.
