Is-it possible to measure accurate strains field by 2D DIC methods at high temperature ?
Résumé
Although Digital Image Correlation method is relatively mastered at room temperature, it is more complex to implement this method at temperatures from 500 • C to 800 • C. The aim of this study is to develop new tools and algorithms to improve DIC accuracy and precision in this temperature range. New methods to implement speckles and new algorithm to decrease errors due to mirage effect are developed. Thes improvements will be used for aeronautical applications.
