Need to add some stuff here...its going on my to-do list! Any suggestions welcome Sam Lacey 00:11, 18 May 2007 (UTC)

Can anyone please verify the origins of this test. I have heard from numerous sources that the test was bought into operation after the Titanic sunk. I believe it was to make sure that the steel used in future vessels would be strong enough to withstand pressure at certain levels. It would be interesting to find out.

According to my professor, it was widely adopted after the Liberty ships were splitting in half; a correlation was discovered such that a particular result on the charpy v-notch test would ensure a sufficiently low ductile to brittle transition temperature to avoid the ship-splitting problem. Unfortunately, I don't have a source on that, and it isn't even the origin of the test, just the origin of its popularity. siafu (talk) 21:45, 21 November 2007 (UTC)
