Image-Based Inertial Impact Tests on an Aluminum Alloy

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 using the virtual fields method, the experimental implementation is detailed. Using the virtual fields method, the yield stress and hardening modulus of aluminum 6082-T6 were identified.
