SHPB / Kolsky Bar Reference Material

REL’s 15 years of experience in designing, building and optimizing Split-Hopkinson Pressure Bar (SHPB) / Kolsky Bar testing systems and techniques has put REL at the forefront of this expanding testing area. Below are references for the theory, setup, calibration, gage mounting, sample testing and software instructions for users performing high strain rate testing on materials using a SHPB / Kolsky Bar.
