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)
“Bourbon’s the only drink. You can take all that champagne stuff and pour it down the English Channel. Well, why wait 80 years before you can drink the stuff? Great vineyards, huge barrels aging forever, poor little old monks running around testing it, just so some woman in Tulsa, Oklahoma can say it tickles her nose.”
—John Michael Hayes (b.1919)
