The VIC3D system can identify regions of high strains that could nucleate cracks or delaminations, Measurements can be made on test articles, components, or full-size structures subjected to simulated or operational loading. We have tested structures as large as 30 ft. diameter rocket tank cylinders to as small as 0.01 inch cracks in pressure vessels. The displacement resolution depends on the size of area imaged and the type of camera used, but a rule of thumb is that resolutions on the order of 1/100,000th of the image area dimensions are easily attainable.
