Stéréo-DIC globale appliquée à l'identification des paramètres d'une loi de comportement

Abstract : The recent development of a global stereo digital image correlation formalism, based on a finite element mesh, allows to measure a 3D-kinematic field directly in the world coordinate system. A benefit of this method is that the experimental measurement is expressed in the same discretization support as the simulation. Then dialogue between tests and simulations is simplified. "FEMU"-like algorithm can be used for the identification of the parameters of a constitutive law. This "FEMU" approach is applied to the identification of the elastoplastic law of an open-hole steel plate. The results are compared to those obtained from 2D-DIC.
