In the second table re theoretical limits α-Fe is listed as having a theoretical value of 2.6 GPa, and a measure value of 27.5 GPa. That can't be right, can it? — Preceding unsigned comment added by 155.4.71.143 ( talk) 14:15, 11 November 2022 (UTC)
Is the meaning of the greek letter 'nu' given anywhere in the isotropic yield criteria? — Preceding unsigned comment added by Jdc2179 ( talk • contribs) 17:19, 7 June 2013 (UTC)
Add a link to the "von Mises stress" page
Do you think it would be a good idea to insert a strain-stress graph? Fractografie 09:16, 12 August 2006 (UTC)
I have recently been working on an article about ultimate failure in materials. Because this is the end result of an overyielded material I was wondering what the best way to incorporate my site within this one was. I was thinking about adding a small section within this article, or just using a sentence or two to embed my site within this one. —Preceding unsigned comment added by Engl315ISU ( talk • contribs) 05:15, 14 April 2008 (UTC)
The two seem one and the same to me. If there's a good reason why that page shouldn't be merged with this, can someone please make the difference between them clear? 217.42.242.45 22:14, 3 May 2007 (UTC)
I see this topic of Yield (engineering) being the main article, and yield surface being part of the yield criterion subsection, where the yield surface is presented for each of the different yield criteria (e.g. Tresca, Von Mises, Drucker, etc)
The development of each of this Yield Criteria can be its own article, or they can just be included within the Yield (engineering) article.

As a large number of yield loci formulations exist, I think the modular structure proposed above would be well suited for future articles in that area. mastic 11:22, 3 September 2007 (UTC) —Preceding unsigned comment added by Mutrux ( talk • contribs)
Yield surfaces are used in other areas of engineering as well, for example in sheet metal forming simulations. Wouldn't it make sense to put the articles in a broader category?

I think this may be the name of the person who added the info about the material "Steel, API 5L X65" to the original table in the tensile strength article. Searching Google, I can't find any non-(wikipedia or copy and paste job) page that returns both API 5L X65 and Fikret Mert Veral. I propose removing it from the table.

Is there a reason the table contains brittle materials such as glass and concrete in an article about yielding (other than that it was copied from the tensile strength article)? I think it's a good idea to remove from the table anything that doesn't have a value for yield. Khakiandmauve ( talk) 18:28, 26 June 2009 (UTC)
Shouldn't the vertical axis be σ=PA not σ=P/A as is the case now? Frankenstien ( talk) 00:15, 11 May 2010 (UTC)
I was wondering if a body of knowledge exists on what I call paradoxical yield. This is when a stretched object 'snaps back' due to structural changes when stretched past the yield point. For instance clothing stretched by surface tension shrinks when the stress is removed. (Examples are harder to find for bodies surviving compressive yield) 24.184.234.24 ( talk) 01:50, 14 April 2011 (UTC)LeucineZipper
In the introduction is the following:
"Besides this we have proof stress. It is that point where 0.2% plastic deformation occurs while returning to its original shape"
If this is correct it needs explaining. How can something that has deformed plastically return to its original shape?
I think that in materials with no clearly defined elastic limit, the yield strength is defined as the stress which causes a 0.2% permanent strain. This might be what the remark refers to, but I don't think it is called the "proof stress".
