ABSTRACT:
An apparatus for monitoring the growth of surface cracks in materials includes a means for applying a load to a specimen to simulate actual use of the specimen, means for illuminating the specimen, means for capturing images of the specimen, and means for processing the images to monitor crack growth in the specimen. Optionally, the means for processing can be used to control the other means.
