Section 2.4.3 of the PROCESS engineering paper explains that

Because the structural material inside the winding pack is assumed to take the form of radial and tangential webs (Fig. 7), the limiting von Mises stress in this zone is given by the larger of the two values:

I think we should adopt the same method when calculating the two Tresca stresses:

  1. Calculate the radial stress in the radial webs, and combine with the vertical stress;
  2. Calculate the tangential stress in the tangential webs, and combine with the vertical stress.

We need to think about how these are derived from the single set of smeared stresses.
