Résumé

This work focuses on experiments developed to better understand the deformation and damage mechanisms leading to failure when stamping 6xxx aluminium alloy sheets. A miniaturized plane strain tensile specimen was developed and validated using Digital Image Correlation (DIC) on the specimen surface to verify the plane strain condition. An in situ tensile test imaged with absorption contrast lab-tomography was then performed on the miniaturized specimen up to failure. Finally, advantage was taken of the plane strain condition to perform two-dimensional image correlation in the material bulk, so called projection-DIC (p-DIC). Intermetallic particles provided image contrast that was registered during the correlation analyses. The p-DIC method was used to compute internal strain fields that were consistent with fracture location observed on the post-mortem scan.
