A uniaxial experiment is performed on an ultra-thin specimen made of 17-7 precipitation hardened stainless steel. An anti-wrinkling setup allows for the characterization of the mechanical behavior with Integrated Digital Image Correlation (IDIC). The result shows that a single uniaxial experiment investigated via IDIC possesses enough data (and even more) to characterize a complete anisotropic elastoplastic model.
Un essai de traction uniaxiale est conduit sur un échantillon en acier inoxydable 17-7 à durcissement structural. Un montage anti-plissement permet la caractérisation du comportement mécanique par corrélation d'images numériques intégrée (CINI). Il est montré que ce seul essai analysé par CINI possède assez d'information (voire plus) pour une identification complète du modèle de plasticité anisotrope.
