Recent Advances and Perspectives in Digital Image Correlation

Excerpt

As evidenced by the articles in this Special Issue, the advent of digital image correlation (DIC) and related methods for accurate, full-field deformation mappings has reverberated throughout the world of experimental mechanics and altered forever the way in which measurements are made and analyses are performed. No longer are investigators limited to average or point-wise measurements on general structures or smaller components. Instead, a new vista of opportunities in measurements and specimen design is opening. Though the paradigm shift may evolve slowly due to the prevalence of existing restrictive standards for certification-bound applications, there is abundant evidence indicating that the process is well underway and is gaining momentum. In the remainder of this Foreword, the editors initially provide a brief introduction to the special issue articles, providing a framework for the issues addressed by the authors and their relevance with regard to DIC methods. Then, the editors close out the Foreword by providing their thoughts regarding past, current and future developments that they envision in the next several years for DIC methods.
