• The uniaxial stress versus strain response of pig skin and silicone rubber at low and high strain rates (2006, methodology): “Pulse shapers take the form of disks of soft materials such as paper, plastic, or copper mounted on to the striker end of the input bar [8,10,58,59].”
• Further investigation on the dynamic compressive strength enhancement of concrete-like materials based on split Hopkinson pressure bar tests. Part I: Experiments (2009, background): “…the nearly constant strain-rate requirement is not always straightforward because it is M AN US CR IP T AC CE PT ED strongly depends on good matching between the dynamic properties of the wave shaper material and the tested material as well as their geometrical dimensions [e.g. Frew et al(2002)].”
• High strain-rate behavior of ice under uniaxial compression (2009, positive): “In view of this, in the present study, annealed copper shims of various sizes were used as the pulse shapers (Frew et al., 2002).”
• Determination of mechanical properties and full-field strain measurements of rock material under dynamic loads (2013, methodology): “Two kinds of pulse shaping techniques, the pulse shaper [24] and a cone-shaped striker [5,25,26], have been used to reduce wave dispersion effect and overcome premature failure of specimen using traditional SHPB [27].”
• A Review of Dynamic Experimental Techniques and Mechanical Behaviour of Rock Materials (2014, methodology): “…pulse shaping techniques, which can be classified into three groups: pulse shaping by placing a thin ductile metallic (e.g. copper, aluminium) disc (Frew et al. 2001, 2002) or a geometrical pulse shaper rod (Gerlach et al. 2011) on the impact end of the incident bar, and using a shaped striker…”
