Dear all,
First of all thanks for taking the time to read my post.
I am doing the checks of direct route, EN 13445-3.But not sure if I should include de static equilibrium check or not, actually, not sure if it makes sense.
The design is a kind of pressure vessel, with a lug type support...
Hi TSG4,
I was now expecting the answer I found you provide several times in the forum: pay for an expert :)
Have a nice day
BTW first question is related to ANSYS software...no need to read a single word from 13445 to answer it...
Dear all,
First of all, thanks for taking the time to check my thread.
I am a beginner with fatigue analysis. I need to obtain damage due to the application of 40.000 cycles of pressure inside a pressure vessel. I am using ANSYS Mechanical for this.
The thing is that I can carry out a static...
Hi TGS4,
Thanks for your advice and for telling me what I have to do.
Do you have an answer/recommendation related to the specific questions posted?
Thanks
Hi hacksaw,
Thanks for your answer, but I don't get the answer to my questions:
1. Is it possible to impose a given number of cycles after a static structural analysis in ANSYS Mechanical to obtain the damage due to fatigue phenomena produced by this given number of cycles? In other words, I...
Hi TGS4,
Thanks for your answer.
I am following 13445-3 Direct Route.
Maybe I am wrong, nut the text mentions a procedure to obtain N (number of cycles)based on strcutural stress, correction factors (welded and unwelded regions...), but I didn't understand how to apply a certain number of...

Thanks for your comments and your advices to search a mentor. Unfortunately, I am not able to get one, si I need to learn this by myself, so I really appreaciate your comments. I have read about 20 papers on the topic just to get informed, but still have some doubts.
I am doing an assessment...
Thanks for all the support.
Finally, I got a converged solution (this is supposed to be enough for one of the criteria specified in the code).
I realized that I have imposed loads for operating pressure, hydorstatic pressure, fixed support and gravity, but it seems that the code multiply this...
Thanks for the answers DrivemeNuts and TGS4.
I would like to explain better: when I talk about Safety Factor I do not refer to the norm. I am talking about the safety factor contours provided by ANSYS Mechanical. And for the loads applied (850 bar+hydrostatic pressure), the Safety factor is...
Dear all,
I am new in ASME BV FEM based analysis.
I have a couple of questions:
1. Is it mandatory to go for elastic-plastic analysis if R/t<4?
2. I have carried out a elastic analysis in a situation of R/t=1,4. The results based on linearized stresses allows the tank to pass (according to...
Hi guys,
Has anybody used this norm(SIA 261) to perform earthquake analysis on a structure based on ANSYS modal analysis+response spectrum? Can you provide any reference on this (paper, tutorial....whatever)?
I guess I know how to solve it but just to make sure I do not miss any important...

Dear experts,
I am a beginner with ANSYS Mechanical. I worked a lot in CFD with FLUENT, CFX, ANSYS ACT (acoustics)...so I am familiar with the GUI and the Workbench environment.
I am trying to simulate a load on a hinge with static structural analysis. Load of 500 kg, applied on an 50 mm long...
