Abstract

The present work aims at identifying an elastic-viscoplastic material behavior over a wide plastic strain and plastic strain-rate range (up to 0.1 and 1000 s−1 respectively), using the Virtual Fields Method. Image-Based Inertial Impact tests have been performed on the Ti6Al4V titanium alloy. The strain-rate dependency of the material has been identified with the results provided by these tests and compared to references.
