[Abstract]:In the stress and strain measurement of modern materials, the digital image correlation measurement method has the advantages of non-contact, full-field, low requirements for experimental conditions, high precision and so on. It is an effective and practical method for measuring stress and strain. It is widely used in experimental mechanics and other disciplines. This paper reviews the development of digital image correlation technology in material stress and strain, compares digital image correlation technology with other measurement techniques. This paper introduces the system structure, correlation algorithm and search method of digital image correlation technology, and lists the latest application and new products of digital image correlation technology in material stress and strain.
