Abstract

The identification of material parameters is very important in order to achieve more realistic prediction of the material behaviour by numerical simulations. An alternative method consists in the exploitation of the strain field measured on a non standard specimen. We have shown in previous studies the improvement brought by the exploitation of the strain field to the quality of the identification of the hardening material parameters [1,2]. The aim of this work is to improve the identification of Hill’s yield criterion parameters using full-field measurements of strain, force-displacement and r-α curves.
