Abstract
This paper presents the development of a novel inertial test for the identification of non-linear parameters for elasto-plastic constitutive models at high strain rates. After briefly presenting the principle of the approach (stress reconstruction from acceleration fields measured using an ultra-high speed camera), the methodology is detailed including the development of the identification routine and the experimental implementation. Results will be discussed and future work presented.
