Extending the annular in-plane torsional shear test specimen to applications at high strain rates

In-plane torsional shear testing is a well-established material technique in the metal forming community. The corresponding specimen designed to be machined from sheet with continuous annular zone intended deform simple shear. Consequently, there are no geometric discontinuities or “edge-effects” induce volumetric changes instabilities result that large true plastic strains up 1.0 can achieved. This paper presents an extension of in-plane test dynamic regime. Dynamic experiments were performed using split Hopkinson bar (TSHB) on specimens manufactured Al 1050 H14. experimental results show adopted used determine behavior accurately and reliably
