Two-wave photon Doppler velocimetry measurements in direct impact Hopkinson pressure bar experiments
EPJ Web of Conferences, 2015 Direct impact Hopkinson pressure bar systems offer many potential advantages over split Hopkinson pressure bars, including access to higher strain rates, higher strains for equivalent striker velocity and system length, lower dispersion and faster ...

New experimental techniques with the split Hopkinson pressure bar [PDF]
, 1984 The split Hopkinson pressure bar or Kolsky bar has provided for many years a technique for performing compression tests at strain rates approaching 10/sup 4/ s/sup -1/. At these strain rates, the small dimensions possible in a compression test specimen give an advantage over a dynamic tensile test by allowing the stress within the specimen to ...

Electromagnetic Compressive Split Hopkinson Bar [PDF]
, 2008 This paper proposes a new design for the compressive split Hopkinson bar that makes use of the intense pressure created in a transient magnetic field formed by the passage of a pulse of electric current through a series of coils.
