FE pipe

Hi,
In my project i have to do trunion on bend calcuation using Kellogs or FE pipe .One of my trunion is failling in Kellogs method and now i have do it using FE pipe .
Does any one know how to set boundary conditions in FE, i need to put forces only or both force and displacements

If you don't know how to use finite elements you should leave it alone. FE-Pipe is excellent software but proper training is essential, otherwise you risk engineering a disaster.

I am working on only one module ie bend with trunions.If you can provide any assistance i will appreciate it.

This is not the place to learn about finite elements. If you did not study F.E. at university, maybe one of your associates did.

Ideally you should contact Paulin Research Group and find out about training courses.

Thanks for your advice and i have downloaded some tutorials form Paulin Research Group.

FE-PIPE is a very comfortable software, I don't think that more FE KNOWLEDGE is necessary if only to a engineering work.

My experience is from NOZZLEPRO which is a part of FE-PIPE and my work is just make basic geometric setting , then read the result.

of course , when I read the result , I need to be familiar with code.

Stress river,

Yours is very dangerous advice. Clearly you are inexperienced and misled.

Without proper training, how could you possibly know whether your FE model is correct, or that you have identified the peak stresses for instance ? It is not simply a matter of looking at a nice colour plot. The mesh density, boundary conditions and nodal locations are paramount. Do you know this ? If so, how did you learn it if FE knowledge is not necessary ?

Your strap line ... Know what you are doing! is a bit of a joke.

Only training is not sufficient. One has to work on various problems under supervision and try to go through the results comparing with codes. FEPIPE has definitely made life easier than modelling every job / componenet in FE. There is no need of being discouraged, patience and time is required otherwise handful of people will be ruling / acting as champions, reality is otherwise - a new starter after sometime overtakes the champions.

"FE-PIPE is a very comfortable software, I don't think that more FE KOWLEDGE is necessary if only to a engineering work"

I think this is why some think to split the stress work in detail design hours and engineering hours.
Regards,

Thanks guys ,
i worked on the FE pipe and it is not that difficult and dangerous.

Nobody has suggested that FE-Pipe is dangerous. It is not. In fact it is excellent software.

However, a little knowledge IS a dangerous thing, made worse by an over-confident manner.

If I will learn to use FE-pipe , I will be a better stress engineer?
