I ran your model through the Sim, and I can't figure out how to see the "colour scale", or the point of maximum stress.... Just a setting somewhere, I assume, can you help?....Bob
I was trying to find if you can attach a model constraint to a mesh node as opposed to a geometry feature (corner, line, face). I think the constraints both Bob and I applied to the right face, over constrain the model and affect the results in the sharp corner. Probably should just constrain the corner. Is there a way to add constraints to the mesh?
Good luck with the repair. My feeble welding skills quickly become plasma cutting on any thin gage material.I did a comparison of the two constraint options for Z. I think the two sets of face constraints (X and Y) for symmetry, provide 5 degrees of freedom so you only need to add the Z at one point. The top image is the Z constraint applied on the entire right face (none on the left). The bottom has a Z constraint on one point, what would be the center if this was a full tube. You can see the expected difference with the doming of the right face. You can also see how much the max stress increased.
When you are using the constraint displacement tool, it lets you select either a face, line, or a vertex (corner) on the geometry just by floating your mouse over it.I think this model should be essentially kinematic, only the one Z point on the right, and the two symmetry X & Y sets on the cut faces. No Z on the left face.My pressure was 60MPa.I need to learn how to run a thermal stress case. One check to make sure the model is not overconstrained, is to apply a uniform temperature change (say 1 deg) and for a single material model there should be no stresses. The analysts used to have a standard set of model checks. I'll have to remember what they were.
Sorry, Left/right as in my picture with the small radius on the right (+Z) side.The analysts I worked with would be chuckling at me right now.

I think you may have Z constraints on both ends, One is across the face and the other on the point. When the pressure expands the tube in Z, the point constraint punches through.
