Digital image correlation in extreme conditions

Digital Image Correlation (DIC) has emerged as a pivotal non-contact, full-field deformation measurement method over the past four decades, witnessing a remarkable expansion in its applications across diverse fields. With the rapid progression of cutting-edge science and technologies, the manufacturing and service environments, as well as the scale and characteristics of critical components are advancing toward extremes. There is an urgent necessity to enhance the DIC method to enable the precise capture of mechanical behaviors and principles under extreme conditions. The difficulties, solutions, and applications of DIC in extreme conditions are herein reviewed, together with a discussion of current limitations and future opportunities.
