ABSTRACT:
A method of measuring dimensional variations in a workpiece in which two spaced points are formed on the workpiece and their images transferred to an image transfer material. After the workpiece has been subjected to a mechanical and/or thermal load and then allowed to return to its original unloaded state, the images of the points are again transferred to an image transfer material and the difference in spacing between the images of the points is compared to ascertain the dimensional changes.
