DESCRIPTION:The properties of soft\, viscoelastic materials at high strain
  rates are important in furthering our understanding of their role during 
 blast or impact events. When testing these soft or low impedance materials
  using a split Hopkinson pressure bar setup one experiences poor signal to
  noise ratios and impedance mismatching when using metallic bars. These di
 fficulties are overcome by useing polymeric Hopkinson bars. Implementing p
 olymeric Hopkinson bars requires characterisation of the viscoelastic prop
 erties of the material used.
