I also have done calculations of a piece of pipe (corroded portion only) in frictionless supports and it ends up in similar way: solution did not interrupt somehow.
I have applied the same BCs to a shell model and it is working as expected. So it is something to do with solid... I also do not get why the solution continues when deformation is beyond material properties or it is not?
1) The boundary conditions are simple: just fixed support and pressure.
2) I have not included pressure trust as I just wanted to experiment with the analysis
3) I have not done anything special, even in the attached file I demonstrated that the geometry is correct, meaning there is no...
Dear TGS4,
I have put some information together in the attached pdf.
edit:
In the solution output I also noticed the below messages which seam to be related. My understanding was that solution would stop if beyond material's max strain but it keeps going on and I even suggested to define more...
Dear all,
I am learning Ansys and trying to estimate pipe burst pressure with FEA. I use nonlinear material as per ASME VII-2 part 5, however my solution does not stop when failure has happened. On the picture it is seen that thee pipe wall is open but I had to interrupt the solver due to...
Dear all,
I am modelling a pipe burst under high pressure, using elastic-plastic analysis. What I observe is that the pipe bursts at one side as if it is more week in that location, however the pipe cross-section does not vary. Can anybody explain this phenomenon?
Another question is can I...
Hi ALL,
I am trying to do nonlinear analysis of a piping element in Ansys but struggling to find plastic properties of A333-6. If anyone has it, I would be thankful if you could share the information here.
