DIGITAL IMAGE CORRELATION APPLICATION TO STRUCTURAL INTEGRITY ASSESSMENT

Digital image correlation represents a useful, efficient, and widely applied method of non-contact strain and displacement measuring in various types of structures. It is often combined with other means of integrity assessment, such as the finite element method and the use of fracture mechanics parameters. This paper presents a short overview of digital image correlation in various fields including mechanical and civil engineering, biomedicine, and some other, more 'exotic' examples. Additionally, some of the examples shown here perfectly illustrate the applicability of this method to cases where high levels of detail and accuracy are necessary in order to measure strain.
