Abstract

Despite the powerful of current calculus codes by finite element or analytical, their reliability and validity must be justified by experimental tests. An original software for the displacement field measurement is presented in this paper. This software use the digital picture correlation principle. Due to this technique, the accuracy of the measure could reach 1/60 th of a pixel and, it is possible to measure strains between 5.10-5 to 0.8. Initially, this software was developed for measuring strains on a sheet testing in metal forming. But, it is revealed that this application field is more important: biomechanical field, geotechnical field, metal characterization, control tests,.....This software could be used, nowadays, for all application whi
