Abstract :
[en] The identification of accurate law parameters for metal sheets in the whole range of their deformation field by just one or two tests would be an interesting progress for the efficiency of forming simulations and manufacturing processes. The final aim of this project is to replace classical experimental homogeneous tests by a few tests performed by single point incremental forming process able to reach very large plastic strains. The identifiability method consists to measure the capacity of a test to identify a material parameter by analysing the sensitivity matrix. In this work, as a first step, this method is just applied on in-plane mechanical tests. Lagamine finite element software developed by MSM team is used to perform the simulation.
