Abstract The dynamic behaviour of Ti-6Al-2Sn-4Zr-2Mo additively manufactured by electron beam melting (EBM) is presented in this study considering synchronised tension-torsion loading. A bespoke spilt Hopkinson Tension-Torsion bar is used to generate combined tensile and torsional stress pulses that interact simultaneously with a novel specimen geometry. High-speed digital imaging correlation techniques are employed to assess the high-rate deformation and crack propagation of the specimen. The material's dynamic response was analysed across a spectrum of stress states, including uniaxial tension, shear, and combinations of tension and shear at strain rates ranging between 500 s-1 and 2000 s-1.
