Title: PROCESS FOR NON-DESTRUCTIVE TESTING USING DIRECT STRAIN IMAGING
Abstract:
A process for non-destructive testing includes applying a photo-curable dye to a surface of an article, selectively curing an array of dots of the photo-curable dye on the surface, removing the photo-curable dye that has not been selectively cured, mechanically testing the article, and direct strain imaging the article during the mechanical testing based on the array of dots.
