Hello!
I need to analyze vessel with bolts. so I need to get pretension stresses in bolts.
I used commands for this - psmesh and sload, but they don`t work. I have read help for a lot of times.
then I decide to create a simple model, but it doesn`t work as well because of constraints.
could you...
Hello everybody.
I have a column vessel. It has the loads: D, P, W.
Let L and T equal 0.
So, I would like to evaluate the column according ASME BPVC VIII div2.
I use elastic-plastic analysis, so I use load combinations from table 5.5.
1) 2,4(P+D)
2) 2,1(P+D)+1,7W
As you know, W has different...
I have a pressure vessel with bent in its shell. So I want to evaluate this vessel acc. ASME BPVC VIII div.2 Part 5 in elastic-plastic method.
My way-
1) I build a geometry model of the vessel with the bent.
2) Use the appropriate procedure describing in ASME
Here I have a question-
When the...
Hello everybody.
I have steel SA-737 Gr.B
Nominal composition is C-Mn-Si-Cb. Well, I use table TM-1 from ASME BPVC Section II part d to know Moduli of Elasticity to use it in calculations.
What string shall I use? Material group A?
Thanks for advance!
Hello!
I have some questions about temperature in pressure vessel.
Suppose that I have pressure vessel which operation (or design - it doesn`t matter) loads only P, Ps, D and T.
to evaluate the vessel I use elastic-plastic analysys acc. ASME VIII div.2 part 5.
So I should use load combinations...
Hello!
Can anybody tell me how to evaluate local criteria (describing in formula 5.6 par.5.3.3) automatically for the whole object in ANSYS?
I found solution for this:
Use Element table. Create formula there and show in final Epeq/El.
But there is a problem - element table can`t involute. So I...
Good afternoon, everyone!
sorry for my English in advance.
I use SHELL181 to find stresses, which I must compare with permissible values in according to ASME chapter VIII.
For this I must separate stresses on membrane, bending and peak.
So, questions:
1) Are middle stresses in shell181 equal...
