International audienceA variational method applied to the identification of distributed material properties is here introduced. This method, established on the constitutive equation gap, has been previously applied by Geymonat et al. (Geymonat et al., 2002) to the identification of elastic parameters. Now extended to a class of elastoplastic behaviour, with linear kinematic hardening, it allows identifying locally 5 parameters from displacement fields obtained during a single test. First, we will present some theoretical notions relative to this identification, and some aspects of the numerical method associated. Then, the possibilities of the method will be presented towards results obtained with a numerical simulation.Dans ce papier, nous...
