Fabrication of samples having material conditions or damage representative of actual components inspected by nondestructive testing involves sensors placed near or mounted on the material surface, such as flexible eddy current sensors or sensor arrays, to monitor the material condition while the sample is being processed. These sample typically have real cracks in or around holes, on curved surfaces, in and under coatings, and on shot peened or otherwise preconditioned surfaces. Processing, such as mechanical or thermal loading to introduce fatigue damage, is stopped once the material condition reaches a predetermined level.
