A split Hopkinson bar could be used for obtaining high strain rate material properties of sheet metals for an autobody. In high speed tensile test of sheet metals, a new tension split Hopkinson bar is needed. From the experiments with the new apparatus, the material properties of SPCEN, SPCC SPRC in the high strain rate state have been acquired and compared with quasi-static experimental results. The experimental results are used to obtain the constraint of Johnson-Cook constitutive relation.
