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.

Famous quotes containing the words compression and/or testing:

    Do they [the publishers of Murphy] not understand that if the book is slightly obscure it is because it is a compression and that to compress it further can only make it more obscure?
    Samuel Beckett (1906–1989)

    No testing has overtaken you that is not common to everyone. God is faithful, and he will not let you be tested beyond your strength, but with the testing he will also provide the way out so that you may be able to endure it.
    Bible: New Testament, 1 Corinthians 10:13.
