Hello Everybody,

                            I will introduce myself to the group, i am sathish

babu working in ASLTOM Projects india Ltd in piping department of plant engineering section.

I am a Graduate Engineer and having a experience of three and Half Years.

Now i am working in CAESAR II stress analysis

When a Forces and moments to be checked ?   to my Idea i usually check on Equipment Nozzles where the piping is to be connected for that i will be defining the nozzle node to have displacement and check in the Restraints Summary for all operating and sustained condition.

Now i faced a small problem , i have angle valve ( Main steam bypass valve dumped to condenser ) while doing analysis i have defined it as rigid component and finished the analysis.

After that the valve manufacturer produced the drawing and asked me to check the allowable forces and moments on the valve.

What i did was went to local element forces and moments and checked the allowable forces and moments on the corresponding node to be OK - Whether This is Right or I have to do anything more

If anyone have any Idea about when this forces and mon=ments to be checked and the basis please explain

Thanking you

Sathish Babu

I have already given myself a stern warning about this, and any further outbursts on my part will, regrettably result in me requesting my resignation. This has been conveyed to me in a formal letter as a first and final warning, so I will not accept any excuses from myself. Sometimes I hate being my own boss.

It sure would be nice to leave this whole national/language mess alone.

If you agree please indicate by not replying.

Cheers

Steve

Maybe all the recent discussion has served to bring out unsaid, possibly

pent-up thoughts and attitudes - it wasn't planned to do so.

I remind everyone that you are all free to unsubscribe at any time.

This discussion list is at about 1100 members now; well over 75% do not ever contribute to the technical discussion. I don't think that 750 sudden unsubscriptions would hurt the quality of the technical discussion.

Then again, it seems to be a free-for-all at the moment and the best move might be to just let it play itself out without possibly heavy-handed intervention.
