Tensile Yielding,tensile Rupture
Tensile Yielding,tensile Rupture
(OP)
hi,
it would be a great help if somebody helps me understanding the following thing,
why tensile yielding is considered as a limiting state when a hot rolled plate is under tensile force where as bolts are only checked for tensile rupture ?
Thanks

RE: Tensile Yielding,tensile Rupture
For a very short element, like a bolt, yielding isn't detrimental. The strain that accumulates over the length of the element at yield just doesn't add up to anything appreciable. So the only concern is rupture.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Thanks a lot KootK.

Can u just make it a little simpler for me. Just for my understanding better....or any reference link will be world of help.
Thanks a lot in advance..

RE: Tensile Yielding,tensile Rupture
1) A bolt in tension connecting two half inch plate. The strain length is very short. At rupture, the bolt might elongate 1/100th of an inch. That's probably not an issue for the structure of which the bolt is a part.
2) An angle used as a 20' cross brace in tension. The strain length is much longer. At rupture the brace might elongate 4". That probably is a problem for the structure of with the brace is a part. Therefore yield is a more relevant limit state for the simple reason that it limits elongation to something much more reasonable.
