    Pretension of bolts (psmesh and sload) in APDL

    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...

    a lot of load cases

    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...

    Bent in shell of pressure vessel (residual stresses)

    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...

    SA-737 Moduli of Elasticity

    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!

    Temperature load

    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...

    Local criteria par 5.3.3 ASME VIII div2

    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...

    SHELL181 and linearization

    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...
