Optimisation et identification intégrée à la corrélation d'images de paramètres de lois élastoplastiques

Abstract : Integrated digital image correlation (IDIC) is applied to identify the constitutive parameters of an elastic and two elastoplastic laws with kinematic hardening. An experiment is conducted on a cruciform specimen in a biaxial setup. The geometry of the specimen is optimized to allow for the least uncertainty in the identification of parameters of linear elastic law. The optimization takes into account the complete experimental and identification processes. Thus, full field measurements, direct numerical simulations and identification procedures accounting for uncertainties, all contribute at their best to the resulting experimental protocol.
