Split-Hopkinson Pressure Bar - Compression Testing

Compression Testing

For compression testing, two symmetrical bars are situated in series, with the sample in between. The incident bar is struck by a striker bar during testing. The striker bar is fired from a gas gun. The transmitted bar collides with a momentum trap (typically a block of soft metal). Strain gages are mounted on both the incident and transmitted bars.
