| Résumé : |
Identifying the mechanical properties of a non-homogeneous structure such as a complex composite lay-up can be troublesome, especially when taking into account defects and damage, which are distributed heterogeneously in the structure. In that context, classical measurement methods are limited and engineers need richer measurement information to validate their simulations. Imaging-based measurement methods can provide this richness, along with interesting input for numerical simulations. |
