Abstrak

An experimental and numerical study on three flat specimen geometries for characterization of the dynamic shear behavior of metals with the use of the compression Split Hopkinson Pressure Bar (SHPB) technique is presented in the paper. The aim of the work is to determine for which specimen shape the most equilibrium state of stress is achieved, and the stress state in the shear zone is closest to simple shear during dynamic deformation. The high strain rate tests were performed on a Ti-6Al-4V titanium alloy, which was deformed with shear strain rate from 9200 to 12,700 s<sup>−1</sup>. The obtained results indicate that the specimen geometry marked as D2S (double-shear version 2 specimen) with double shear zones guarantees high quality of the obtained experimental data.
