WhatsApp: +86 18838072829The lower limit of SHPB. The absence of machine structure and measuring instruments in the SHPB technique allows measurement at high strain rate and is limited only by the radial inertia of the test bars due to the Poisson ratio effect. The upper limit of strain rate for the SHPB technique is approximately 10 −5 s −1 for a material that has high sound speed (Gray, 2003).
