Hello, thank you for your comment! Yes, it is possible to apply the Structural Steel NL material model to such a problem. This would be acceptable in an academic scenario but would be of little value if meaningful results are necessary. As suggested in the video, the weld material should be characterized with regard to elastic modulus as a function of temperature, TCE as a function of temperature and plastic stress/strain as a function of temperature.
Hello, thank you for the video. I would like to clarify about the residual welding stresses. As you have shown, the values of these stresses are high. As I can rememeber the welding stresses are self balancing onces. Therefore, when assessing the strength of a welded joint, they are not taken into account. Can you please comment on this issue?

A second model could be developed, considering heating the plates before welding them and checking the final stresses after the slow cooling process of the entire joined piece. What do you think?
Hi, and thank you for your questions. Yes, that’s certainly possible. You would need to set the initial body temperature of the plates. If you were interested in any time domain effects, it would be required to run a transient thermal analysis and apply these to the structural analysis to then perform the thermal stress analysis and capture the time history of the cooling process.

Interesting approach, thank you for sharing
Good job
Hello Sir. Is it possible to apply "Structural NL steel" for welding material in Ansys?

@@SimuTechGroup Thanks. Got it. By the way, What does it mean TCE?
@@Munkh-UnurTogtokhbuyan thermal expansion coefficient?
Excuse me can you describe what 3 displacement that you used in that video? Thx

I see the mesh of the fillet is not conformal with the vertical and horizontal plate?
Dont need some radios in the critica zone? I mean the toe of the welding

If you showed this from the start then it would’ve been the best ansys video out for sure but no
