[edit] Materials science

Materials science differs from this in what way? —Preceding unsigned comment added by Sparky (talk • contribs) 07:50, January 22, 2004

  1. Materials science is far broader.
  2. Academically, they are taught as different subjects.
  3. In the real world, engineers use these disciplines separately; Materials science involves the development or choice of materials for engineering uses, and Strength of materials is applied to the design of mechanical elements. They are sometimes used in parallel and sometimes overlap. For example, a design engineer choosing a material for a specific application. But they are not the same subject. Professionally, material science is a different occupation than Design engineering or Analysis.

  1. Tensile Strength is a very important test for many materials (suture materials for example) Merging this article into strength of materials would be a diservice to the community. Are we going to start a trend of merging all subtopics into their parent topics? Who wants to read a 60 page article on all the types and measurments of a material's strength?

[edit] elasticity/plasticity edit

I decided to replace the existing text with a plain-English explanation of the concepts of elasticity and plasticity. I also deleted the paragraph about viscosity. Although I can see why creep is relevant, I did not feel like taking the effort to massage it into the section. Viscosity relates to fluids, and the article relates to solids, so I think it is out of place.

I will sign this properly when the servers come back up. Cbdorsett

[edit] Proposed merger

No support, I am calling off the merger and removing the links. Georgewilliamherbert 01:29, 22 September 2006 (UTC)

[edit] Fixes and additions

I fixed a bunch of stuff that was clearly wrong, and took out some stuff which didn't make sense.

I removed the part about Hooke's Law, as it doesn't belong in a strength of materials article, and will only confuse readers about the stress-strain relationship.

I also removed the comment about compressive stress that stated a material under compression will decrease in volume. This is simply wrong and needed to be removed. Sorry if I stepped on any toes, but I looked this up at work and my head almost exploded when I read it.

Most materials will in fact decrease in volume under compression. Look up the article on Poisson's ratio on wikipedia or google "volume strain". In my opinion, Hooke's law should be mentioned, as well as basic structural analysis methods. This article should reflect the topics covered in common ""Strength of materials"" engineering courses and books, which focus on stress-strain relations, beam and truss analysis, continuum mechanics, and material strength terms.

[edit] Structural strength

A search for "structural strength" gives no useful results. My context is the use of that term on the hardboard article. Perhaps the term should be explained in this article?

[edit] Case studies

The article is far too theoretical, so I have added an external link to real case studies of failure. The article itself also needs some cases as well. Any offers? Peterlewis 14:43, 20 June 2007 (UTC)
