| Abstract: | A split Hopkinson tensile bar of reflective type is developed for high strain rate tensile testing of materials. Tests on 1Cr18Ni9Ti stainless steel are performed. Problems such as the interfering signals from the connexion of specimen, the determination of dynamic strain and the 2 dimensional effect from the geometry of specimen, are discussed. |
