Dynamic mechanical behavior of pure titanium

The compressive dynamic mechanical behavior of α-titanium with more impurities was carried out using a Split–Hopkinson pressure bar (SHPB). A cylindrical specimen was set between the incident and transmitted bars and impacted at high strain rate (∼103s−1) The test revealed significant rate sensitivity of the fracture and linear strain hardening, and the critical strain rate at fracture was determined to be 3000s−1. The failure model was by …
