The Split Hopkinson Pressure Bar (SHPB) experimental setup consists of several primary components. At the heart of the setup are the incident bar and transmission bar. The incident bar is the first bar struck by the projectile, which generates stress waves that propagate through the specimen and into the transmission bar. The specimen, the material being tested, is placed between the incident and transmission bars to experience the stress waves generated by the impact. Tension grips or fixtures securely hold the specimen in place to ensure uniform loading during the test. Strain gauges are attached to the incident and transmission bars, to measure the strain response during the impact event. 

For dynamic tests, a gas gun is employed as a launching mechanism to accelerate the striker before impact. It propels the striker using compressed air.  The data acquisition system records signals from the strain gauge sensors during the test, capturing high-frequency data for analysis. Prior to conducting actual tests, a calibration standard made of a well-characterized material is used to validate and calibrate the SHPB setup. 

Proper alignment, calibration, and synchronization of these components are crucial for the success and reliability of SHPB experiments.
