An ordinary rod torsion problem, the tresca stress result on PrePoMax doesnt seem to be true, when running the ccx results that is found in the “Temp” folder the tresca stress (maxShear) is the correct one, so is that a bug or there is something that I dont understand?
Check this thread: Tresca Stress Result
As FEAnalyst wrote, there is not a single Tresca definition.
I am moving this topic to General questions.
