The conventional SHPB technique is improved by using a pulse shaper. Pulse shapers technique is used to modify the incident wave and decrease the effect of wave dispersion to ensure stress equilibrium and homogeneous deformation in specimen, and furthermore a constant strain rate is attained during the loading history. The lasting time of acceleration pulse is enhanced to numerable MSEL, which is more close to actual loading.
