Abstract

The quasi-static compressive and dynamic compressive (SHPB) experiments were carried out to investigate the static and dynamic property of titanium alloy Ti6Al4V though analysis and comparison of the experiment results, the Johnson-Cook constitutive model of titanium alloy Ti6Al4V was established. The cutting process of titanium alloy Ti6Al4V was simulated using the orthogonal cutting finite element model. Though the simulation, the Johnson-Cook model considering the adiabatic effect was more correct. The establishing of Johnson-Cook model provided the conditions for the further simulation and parameters optimization of cutting process of titanium Ti6Al4V.
