Controlling testing machines with digital image correlation
The aim of this paper is to show the feasibility of controlling strains in a mechanical test using digital image correlation (DIC). A software, called CORRELICONTROL, was developed and is presented herein. It is validated by driving a tensile test on a steel sample. A first part is devoted to the description and performance of the correlation algorithm used in CORRELICONTROL. In particular, the correlation parameters are chosen and the strain uncertainty is determined a priori. Cascade feedback architecture is introduced, tuned, and characterized in a second part. In the last part, a tensile test on steel is controlled via CORRELICONTROL.
