Inverse Identification at Very High Strain Rate of the Johnson-Cook Constitutive Model on the Ti-6Al-4V Alloy With a Specially Designed Direct-impact Kolsky Bar Device

Résumé

In the present work, an inverse identification of the Johnson–Cook constitutive model is performed on the titanium alloy Ti-6Al-4 V at three strain rates until about 2·10 4 s-1 (till about 1.1·10 4 s-1 of plastic strain rate) on a specially designed direct impact Kolsky bar device. First, the design of such a device must meet several criteria, and is shown to be the solution of an optimization problem. A systematic design procedure for such a device is then introduced. Second, an inverse analysis using the finite element code ABAQUS is carried out to identify the Johnson–Cook parameters on experimental data obtained with the designed system.
