FE DIC for strengthening the experiment/simulation dialog: application to composites

Jean-Noël Périé

Résumé

Digital Image Correlation (DIC) nowadays appears as a very convenient counterpart to FE simulation for validation or identification purposes. Nevertheless, DIC strain resolution is high compared to the strains met in composite structures, and classical subset based DIC are not convenient to couple with finite element (FE) simulations. With the emergence of FE-Stéréo DIC (FE-SDIC) approaches, and the use of multiscale measurements, it now becomes possible to make objective and quantitative comparisons between computed and measured displacements. In addition, FE-SDIC also makes it possible to regularize the measurements using part of the model. This makes it easier to assess mechanically consistent boundary conditions. The example of the experiment/simulation dialog proposed structural test perfomed during the ANR VERTEX project is presented.
