Talk:Fracture toughness

From Wikipedia, the free encyclopedia

Could somebody cite sources for the table? Granted, most of the materials listed are not exact alloys, but the values are very different from values I have seen in a different source. Hithisishal (talk) 08:20, 27 January 2008 (UTC)

Looks like it is taken from this web page http://www.sv.vt.edu/classes/MSE2094_NoteBook/97ClassProj/exper/mcmurtry/www/matt.html The page specified actual alloys. Belchja (talk) 21:06, 6 June 2008 (UTC)

I have added material previously in the article on Fracture Mechanics. It is more appropriate here.

- I have added links to Charpy and Izod tests but maybe a new subsection on this would be better - then delete the original pages?

It is useful to include the units written as Nm-3/2 - which are the same. The suffix "1" does indeed refer to mode one crack opening but the "C" denotes the critical value showing that, for crack propagation, the stress intensity factor [Y(Pi.a)1/2] must become equal to the Fracture Toughness (EG)1/2


It would be helpful for a description of the criteria required for an accurate KIC test based upon the ASTM standard —Preceding unsigned comment added by 129.22.154.234 (talk) 16:23, 7 May 2008 (UTC)
