Abstract: Split Hopkinson Pressure Bar (SHPB) has become a frequently used technique for measuring an uniaxial compressive stress-strain relationship of various engineering materials under high strain rates, the pulse shape is sensitive to the length of striker bar. In this thesis, a finite element simulation of a Split Hopkins Pressure Bar is performed to estimate the effect of varying lengths of striker bar on the stress-strain relationship of a material. A series of striker bar with lengths from 200 mm to 350 mm are utilized to obtain the stress-strain response of AL6061-T6 in both simulation and experiment. A comparison is made between the experimental and computed strain waves. Consequently, the influence of variation of the striker bar lengths on the sample stress-strain response is presented.
