Abstract : The behavior of Ti-6Al-4V has been studied via shear tests, using hat shaped specimen, on a servo-hydraulic Gleeble 3800 testing machine under the strain rate up to 10(3)s(-1) and temperature up to 900 degrees C. A new thermo-visco-plastic material law is proposed, based on a modified Johnson-Cook formulation. An inverse identification method based on Finite Element (FE) is established and detailed in order to determine the constitutive law's parameters. The new model is implemented in a 3D finite element model to study the chip formation in orthogonal cutting configuration. The numerical simulations were performed on FE software Impetus Afea (R) able to solve dynamic non-linear problem.
