摘要：
In order to describe the stress flow behavior of TC4 titanium alloy reasonably, firstly,universal material testing machine and split Hopkinson press bar (SHPB) facility were respectively used to conduct normal and high temperature quasi-static tension and dynamic compression test. Engineering stress-strain curves at different strain rates and temperatures were obtained by experiments. It reveals that the strain hardening effect of TC4 titanium alloy is weak, but the strain rate sensitivity and temperature softening effect are strong. Secondly, basing on the experimental results, the Johnson-Cook constitutive model (J-C) was modified to obtain the MJC model, and also the parameters of J-C and MJC models were calibrated by numerical simulation. Finally, in order to verify the mode and its parameters, the model of plate impacted by projectile were established with ABAQUS/Explicit finite element software. Moreover, the J-C and MJC models and parameters were embedded into the finite element program respectively for numerical simulation, and also the experimental results were compared with numerical simulations. The results show that the ballistic limit of projectile and the failure mode of plate predicted by MJC model are closer to the result of experiments than J-C model. © 2020, Editorial Office of Journal of Vibration and Shock.
