Talk:Fracture

message: Wow, this has been a big month for this article.  Good job, guys!  Would someone care to mention transgranular vs. intergranular?  I used to know this, but I've forgotten a lot and don't want to embarrass myself writing false information.--Joel 22:13, 2 Jun 2005 (UTC)

message: What is refered to here as "Ductile Fracture" is what I know as "Rupture." The topics are sufficiently different that I think a seperate rupture article should be started and the ductile fracture stuff moved there. --Yannick 01:40, 2 December 2005 (UTC)

message: Does fracturing in geology include information that isn't in this article? A lot of geological articles are linked here. -- Kjkolb 09:35, 14 December 2005 (UTC)
replies: text: I made a new article, Rock fracture, to address the specific context of fractures in geology. I'll try and re-direct geology related links there; and please, contribute to that article. +mwtoews 03:23, 14 September 2006 (UTC)

message: Hi there, I am looking at the formula for critical stress required for crack propogation in this article and it does not match what I have in my college text book.
I have not figured out how to use greek letters yet, but basically the formula I have is
(Critical Stress)=sqrt(2*(Modulus of elasticity)/(specific surface area)/(Pie*(half crack length)))
This formula is according to William D Callister Jr, in his book Materials Science and Engineering.
I actually like the formula given by wikipedia a little bit better because it includes the radius of the crack tip in the calculation, however I think that it might be appropriate to include this alternate formula which, eleminates the interatomic distance as well as the crack tip diameter as well so as to be a little bit more complete.
But this is my first time ever typing into wikipedia, so I was just wondering what all you other experts in material science think about this idea? —The preceding unsigned comment was added by Hobojaks (talk • contribs) 03:32, 27 March 2007 (UTC)

message: === Cup-and-cone ===
I'm not sure saying that it results in a rough surface is accurate. This statement kind of implys a brittle fracture. More description of a cup-and-cone failure might be more desirable for this article.132.170.7.254 14:42, 23 March 2007 (UTC)

message: "A fracture is the (local) separation of an object or material into two, or more, pieces under the action of stress." Could someone kindly defend the inclusion of "(local)" as we can cite many examples where fracture goes way beyond "local".

message: I suggest referring to the wide variety of failure modes such as fatigue, environmental as well as ductile and brittle. You could lead the reader to looking at existing pages with more specific information in it. Lwcheung (talk) 07:03, 30 October 2017 (UTC)

message: Could someone have a look at Draft:Rubbery state fracture? This draft looks ready for mainspace, but I would appreciate if someone could perform a sanity check on it as it's way beyond my subject area. I'm a bit concerned about the fact that the phrase "rubbery state fracture" shows virtually no results on google scholar or google books. – Uanfala (talk) 00:51, 27 December 2017 (UTC)

message: Hi Dawnseeker200. Why you just keep reverting the text while i'm trying to put "something" in the Fracture page. Because the crack can also occur on even walls and ceilings, i have to put it in there. But then you revert it back to the standard revision leaving only surface. Please force me to put it back now. Comment a reply for any reasons why is this happen. Dester12 (talk) 19:33, 12 May 2023 (UTC)
replies: text: Hi I reverted it because of the broken English. In other words, it was less clear than the original and I didn't consider it an improvement. It did not mean to step on your toes; just trying to keep it readable and understandable. Dawnseeker2000 21:17, 12 May 2023 (UTC)
replies: text: Okay then Dawnseeker2000. But rather than cases sometimes crack can appear on walls and ceilings so we put "something" word to consider the cracks on walls and ceilings meaning in terms for American English and British English and no words are unclear. That's okay. But if not putted instead, then it only occurs on the surface, that's a big no. Once again, we used that word to indicate that a crack usually appears on walls and ceilings. Reply a message that is right with reasons please. I swear god. :( Dester12 (talk) 21:32, 12 May 2023 (UTC)
replies: text: , your English languages skills are not adequate for editing the English Wikipedia. I recommend that you edit the Wikipedia in your first language. On the specific point, walls and ceilings are surfaces. The word "something" conveys no useful information, and is poor writing in this context. Cullen328 (talk) 21:44, 12 May 2023 (UTC)
replies: text: Oh, okay sure Cullen328. I get it at this point. Dester12 (talk) 22:55, 12 May 2023 (UTC)

text: Also Cullen328. It can also occur on objects like pencils, crayons, pots, etc so that's why we uses "something" word. It is true sure by writing in a reply message. Dester12 (talk) 23:07, 12 May 2023 (UTC)
