CAn U help me with examples?
of bending pipes and pipelines, natural frequencies analisys..
and etc ..but examples from real life, or theoretical ones from book,,please give a link...if U have.

Check the \caesar\examples directory. The jobs NUREG9 and HAMMER both involve natural frequencies.

I've already checked... but where I can see this paper (article Nureg from August1980 ?? I have tried to find but with no results..
I saw all examples in CAESAR))

The NUREG documents are very hard to find. They were published in 1980 and additionally in 1985. These manuals contain a short explanation of the model, associated assumptions, and then the input and output from a "MainFrame Computer Program" (ESafe if I remember correctly - sorry, I'm not in the office right now) that was used at that time.

Do you have specific questions? What are you looking for?

I'm looking for "easy" (if I can use this word) examples of static structure and dynamic (modul) analysis ofpipe and pipelines...
I'm only a beginer and that's why I'm compearing result with CAESAR II Ansys and theoretical result. That is why I need this staff: papers articles or reports, where I could find analitical solution of tast ( which kind I wrote abowe).
Please, If U have any - give me a link...
I solve some tasks, with cantilever ,for modal and diplacement. as I wrote U L beam, also I have partly solved J-beam problem as U possibly remember I was asking a lot about it.
found natural frequences of T - beam clamped everywhere and so one..
all this I done, but possibly U have examples ( I'm sure U have solved a lot off such task being an coade enginier) publications...all this I need only for studing..
So...that all I whant...)) for begining ..of cause if it is not diicult for U..
