I have revised the Introductory section in order to emphasize that Fracture Mchanics has equal parts of materials science and solid mechanics. I also have a problem with the statement that Fracture Mechanics has uses in design of new materials. This may be the case, but I would be happier if some examples had been provided.Al Rosenfield 21:13, 21 November 2005

The article needs to be extended to include elastic/plastic and fully-plastic regimes. Also, the discussion of crack origin needs to be extended.Al Rosenfield, 29 NOV. 2005

I have taken material from this section and put it into the article on Fracture Toughness, where it is more appropriate. Al Rosenfield 21:10, 3 January 2006 (UTC)

I see no mention of E. Orowan's contribution to fracture mechanics. He modified Griffith's equation by adding the necessary plastic work required to extend a crack wall. This was proposed in E. Orowan, in "Fatigue and Fracture of Metals," Symposium at Massachusetts Institute of Technology, John Wiley & Sons, Inc., New York, 1952. I would like to add some details about his modifications from G.E. Dieter's Mechanical Metallurgy (1988 McGraw Hill) Sirkha 02:23, 10 December 2006 (UTC)

[edit] Is fractal mechanics this?

Coming from the article Alexander Balankin, I was non-plussed at the term "fractal mechanics". After a moderate amount of Googling book/article references, there must be such a thing. Is fractal mechanics the same as Fracture mechanics? If so, a redirect is warranted. However I don't see the term 'fractal' used as such in this article. Shenme (talk) 07:43, 16 February 2008 (UTC)

[edit] Griffith's theory ignored?

According to the Alan Arnold Griffith article, his work led directly to changes in engineering design, rather than being ignored as it says here. I have struggled to find support for either viewpoint. Anyone able to help me out? Mikenorton (talk) 16:16, 27 May 2008 (UTC)

I'm adding a paragraph from Prof. Erogan's Fracture Mechanics, Int. J. Solids Struct., 2000, 37, p. 175 in support of the ignored thesis. Bbanerje (talk) 06:30, 30 May 2008 (UTC)

Thanks for that, and all your other efforts on this page. Mikenorton (talk) 10:57, 1 June 2008 (UTC)
