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 difficulties are overcome by useing polymeric Hopkinson bars. Implementing polymeric Hopkinson bars requires characterisation of the viscoelastic properties of the material used.
