We develop the Finite Elements Stereo Digital Image Correlation (FE-SDIC) method with two purposes :
First, validating the numerical models by measuring the displacement field directly comparable with usual simulations. Stereo extends the scope of DIC to non-planar cases, which are more representative of industrial use cases.
Second, getting the boundary conditions on the technological specimen, needed by the numerical model.

In order to expand our knowledge of the structure behavior, we are working on a multi-scale approach coupled with infrared thermography.
- Figure 2 - Example of a multi-instrumentation. Here a couple of cameras observe the whole zone of interest, another one, with higher resolution, watches the damaged area and an IR camera is in the center.
