Merged with elasticity (solid mechanics)

Some material has gone to the stiffness article.

I don't think I have removed any information that isn't-now / wasn't-already somewhere else, though I have moved things round a bit.

We seem to have hundreds of articles on things very closely related to elasticity, so I made this more of an overview and a set of pointers.

Elasticity is a branch of physics which studies the properties of elastic materials. A material is said to be elastic if it deforms under stress (e.g., external forces), but then returns to its original shape when the stress is removed. The amount of deformation is called the strain.

Modeling elasticity The elastic regime is characterized by a linear relationship between stress and strain, denoted linear elasticity. This idea was first stated by Robert Hooke in 1676 as an anagram, then in 1678 in Latin, as Ut tensio, sic vis, which means: —Preceding unsigned comment added by 202.84.110.216 (talk) 07:53, 3 March 2008 (UTC)[reply]

Bernouilli's law picture

Just a question. What is the real relationship between elasticity and Bernouilli's expression? I don't understand the presence of that picture here. Fiquei (talk) 11:46, 25 November 2009 (UTC)[reply]

We can assume or upload a photo of a pipe with different radius of both ends in which the end through which the water enters should be with larger radius as compared to radius of water outgoing or existing radius. Sonu PD. Yadav (talk) 12:24, 19 March 2017 (UTC)[reply]

Units of measurement

It would be nice if the units of measurement of elasticity were introduced.Tedtoal (talk) 04:07, 12 October 2011 (UTC)[reply]

Needs some reviewing

The entire article is very poorly worded and missing a lot of information. An expert is needed to fill in some of the gaps. 1.162.89.147 (talk) 09:01, 16 February 2012 (UTC)[reply]

I tried to encapsulate the problems in a multiple-issues tag, but there is no tag for the main problem: This article is mainly a series of dictionary definitions, each with its own section. It has no cohesion. RockMagnetist (talk) 23:45, 22 February 2012 (UTC)[reply]

Copyright violation

I removed some material that violated copyright. Here was the text:

In general, if a stress is applied to an object, the strain will increase in proportion (see illustration) until a certain point called the limit of proportionality is reached. This is in accordance with Hooke's law. Thereafter there is at first a slight increase in strain with increased load until a point L is reached. Point L is called the elastic limit. Up to this point, the deformation of the specimen is elastic, i.e. when the stress is removed the specimen returns to its original length. Beyond point L there is permanent deformation when the stress is removed, i.e. the material has ceased to be elastic and has become plastic. In the plastic stages individual materials vary somewhat.In general,however,at a point B there is a sudden increase in strain with further increase of stress.This point B is called yield point. Beyond point C, the Breaking stress, the wire will snap(which occurs at point D). Point D is called Breaking point.

and here is the text from the Oxford dictionary of science:

In general, if a
stress is applied to a wire, the *strain will increase in proportion (see OA on the illustration) until a certain point called the limit of proportionality is reached. This is in accordance with *Hooke’s law. Thereafter there is at Ürst a slight increase in strain with increased load until a point L is reached. This is the elastic limit; up to this point the deformation of the specimen is elastic, i.e. when the stress is removed the specimen returns to its original length. Beyond the point L there is permanent deformation when the stress is removed, i.e. the material has ceased to be elastic and has become plastic. In the plastic stages individual materials vary somewhat; in general, however, at a point B there is a sudden increase in strain with further increases of stress – this is the yield point. Beyond the point C, the breaking stress, the wire will
snap (which occurs at point D).

Rewrite and new sections

I went ahead and rewrote most of the article apart from the section on Hooke's Law (which, I think, places undue emphasis on it, but I am wary of removing a properly referenced section from an article tagged for not having enough citations). I also added an overview section with some sourced examples. Hopefully this addresses some of the numerous complaints that the article is too complicated and that it has zero examples in the feedback. -Anagogist (talk) 21:49, 24 November 2012 (UTC)[reply]

Article would benefit from explaining difference between elasticity in physics and common use

The physical definition of elasticity is unfortunately very different from the common usage of the word. Just confront 100 people on the street with the statement that quartz is the most elastic material in the world. 99 will say you are crazy while 1 physicist will say it's correct. The article would greatly benefit if this apparent paradox where straightened out at the beginning of the article.

Does anybody have a good explanation for why elasticity has such contradictory uses? — J.S.^talk 10:43, 20 November 2018 (UTC)[reply]
