文摘

A multi-camera DIC system used to measure the whole-field thickness strain is proposed with its theory in detail. Whole-field thickness strain is measured with its strain history. Whole-field quasi 3D strain history is acquired. Provide a new convenient method in thinning limit determination of sheet metal.
