Thanks for the confirmation.

where can i find this code? i need to have a look at AD-610 (Figure AD-610.1)

How can we obtain the above mentioned stresses using ansys workbench.

thanks everyone, got a lot of quality inputs. will change the boundary conditions and will let you know the results.

Thanks littleinch, will keep it in mind.

so this analysis cannot be done using static analysis using sensible assumptions right? will have to go to transient right?

Thanks tgs4

sure, will look at that. thanks

yes, roarks provide solutions based on linear elastic theory. roarks consider deflections greater than half the plate thickness as large deflection, and certainly the deflections which i get will me far higher than that. Am not familiar with other theories dealing with very large deflections. i...

Actually, our scope is to use fea to find out whether the flange is safe for operation or not. since the code requirements are conservative, by using fea we can be confident whether to use it or not. The flange rating was provided by our client. And dont know why you are getting offended. Am not...

i need to analyse a circular membrane of 72m dia and 7mm thick using shell element in ansys workbench. the edges are fixed. I am getting very large deflections at the bottom. i have turned on the large displacement option 'on' in analysis settings. am not able to validate the result with roarks...

sorry to bother you again. can you please elaborate? the operating temp is 43.33 deg celsius and 3670 psig. according to its pressure temp rating it can withstand a pressure of 3634 psig at 50 deg celsius. so its very much at the brim of its limit. so we need to perform fea, and find out...

in the pv elite software also, wm1 and wm2 are calculated. let me go through the document which u suggested. can you just go through page number 376 of asme sec viii div 1 ? thanks in advance.

thanks a lot petr.

in the pv elite report from our client, the flange fails due to less bolt area. it is a standard 4inch 1500 pound welded neck rtj flange. we need to show that its safe for operation acc to asme sec viii div 2.
