A new split Hopkinson tensile bar design
International Journal of Impact Engineering, 2012 This work presents a new design for a split Hopkinson tensile bar (SHTB) as well as generated representative experimental results. The new design uses a U shaped striker bar as projectile and addresses several shortcomings of classical SHTB designs using hollow striker bars.
