Methods that provide wrinkle characterization and performance prediction for wrinkled composite structures using automated structural analysis. In accordance with some embodiments, the method combines the use of B-scan ultrasound data, automated optical measurement of wrinkles and geometry of cross-sections, and finite element analysis of wrinkled composite structure to provide the ability to assess the actual significance of a detected wrinkle relative to the intended performance of the structure. The disclosed method uses an ultrasonic inspection system that has been calibrated by correlating ultrasonic B-scan data acquired from reference standards with measurements of optical cross sections (e.g., micrographs) of those reference standards.

An apparatus for evaluating a part may include a camera, a camera-holding member for holding the camera in place relative to the part being evaluated, and an indexing surface disposed in a fixed position relative to the camera-holding member. The camera may be positioned to take a simultaneous picture of both the indexing surface and the part in order to evaluate the part using the picture by comparing an indexing surface image with a part image.
