Estimation of elastoplastic parameters via weighted FEMU and integrated-DIC. Mathieu, F., Leclerc, H., Hild, F., & Roux, S. Experimental Mechanics, 55(1):105-119, 2015. abstract bibtex ? 2014, Society for Experimental Mechanics.DIC-based identification of the constitutive parameters of an elastoplastic law is addressed both from a general viewpoint, and applied to the particular case of dog-bone sample made of commercially pure titanium and subjected to tensile loading. A two-step procedure (Digital Image Correlation ? DIC ? followed by weighted Finite Element Method Updating ? FEMU) is first presented. These two steps can be merged into a single-step procedure (i.e., Integrated-DIC or I-DIC). In both cases, the elastoplastic computations are performed with a commercial code (i.e., non-intrusive identification). When the suited weighting of FEMU is taken into account, which is based on DIC-processed image noise, both I-DIC and FEMU methods provide similar results. It is shown that the addressed experimental case requires the use of static (load) information to get precise estimates of the sought parameters.
