TGS4, I have not read the paper you mentioned. Referring to Table 5.3, design load combination 1,3, and 6 apply to my analysis. Can you confirm if I am using correct allowable stress for each load combination? 1)P+Ps+D: PL+Pb<1.5S 3)P+Ps+D+L+T: PL+Pb+Q<2Sy 6)0.9P+Ps+D+0.7E: PL+Pb<1.5S

corus, The pressure vessel I am analyzing has nozzles at the heads and near the heads so we decided to use FEA. TGS4, I was looking at the 2008a addenda not 2009b addenda and you are correct about the pressure. I was told to analyze plastic collapse using elastic method so I followed Table...

Dear TGS4, Thank you for the information. I will read the Part 5 of Div. 2. We are to design the pressure vessel using 2007 edition with 2009 addenda. So you are saying I should use 2.9 psig design pressure for internal pressure NOT calculated MAWP and MAEWP? But the Table 5.2 describes P =...

Dear TGS4, I'm new to both, as my experience was using FEA for consumer product design but somehow my company thinks my experience is suitable for pressure vessel analysis. I know it requires experienced engineer to design pressure vessels so your input will be greatly appreciate it.

thank you Fawkes for the clarification, I will run the analysis with different load combination.

innovation2, According to ASME VIII-2, Table 5.2, P = Internal and external maximum allowable working pressure, so I assumed I can apply both loads at the same time.

I'm new to analyzing pressure vessel using ANSYS and had few questions: 1) The design pressure of the vessel is only 2.9 psig. I calculated MAWP to be 313 psig and maximum external pressure to be 205 psig, both hot & corroded condition. My manager thinks for FEA, I can just apply internal...

Does ANSYS Workbench have option of mid-plane shell mesh or surface shell mesh similar to COSMSOWorks? If so, what are the steps using GUI?

I completely uninstalled COSMOS and clean the registery but still not working. My IT person ended up installing in the virtual pc and it worked. COSMOS must be clashing with other applications in my computer IT person thinks.

Hi, COSMOS tech support was unable to help as COSMOSDesignStar 2007 that was installed in my computer does not show Analysis tab when I start the program. The program worked fine since I used last time about 9 months ago. I have since re-installed the program two times but to no avail. Only...

corus, Thank you for your suggestion. So I put loads on BOTH ends of the pipe? The pipe is modeled as 34 feet long.

corus, The problem at hand is to find the maximum stress of the pipe shoe (see attached picture). Manufacturer of the pipe shoe has specified vertical, axial, and lateral load that pipe shoe is deigned for and I'm trying to verify these loads. In real life, I guess pipe is filled with water...

Hello, I'm new to FEA and need help applying loads in horizontal pipe. How do I apply vertical, lateral, and axial loads on a 30 feet long pipe. I have model the pipe and need to know if I need to select outer surface, inner surface, and or a faces of the pipe and apply a load?
