Since Tesca stress is the stress used in the Tesca yield criterion, it is often taken as the synonym of the max shear stress. I think "Tresca stress × 2" is exactly the name that represents the stress calculated currently under the name of "Tesca s…
Here is textbook that refers to Tresca stress as the max shear stress (see attached for a copy of the text):

Hi Victor,
My understanding is that Tresca stress is by definition the max shear stress. Thus, it is one half of the difference between the 1st and 3rd principal stresses. This should be mentioned in any advanced strength materials where the criter…
