Identification of crystal plasticity law parameters using kinematic measurements in polycrystals

Abstract : From tensile tests on stainless steel specimen performed in-situ in a scanning electron microscope, displacement fields are measured using digital image correlation with an unstructured mesh taking as support the microstructure of the material. With this same mesh, finite element simulations are then performed using a crystal plasticity law and with experimentally measured boundary conditions. The comparison of measured and simulated displacement fields leads to the identification of the sought parameters by resorting to a weighted finite element model updating method
