Paper Abstract

A number of "aided visual" techniques are at the disposal of the control engineer when surface or near-surface cracks have to be detected. In increasing order of sensitivity and sophistication we can cite dye penetrants, magnetic inspection, specimen grid moire, speckle correlation, interferometry and holographic interferometry. Those methods have the common advantage to allow full-field inspection, as opposed to point-by-point techniques; a permanent record of the test can be obtained, allowing a posteriori inspection and/or follow-up of the defect.
