Just trying to understand why Mecway can calculate Von mises equivalent stress in shell eles but not Max shear stress x 2 ?
Also might it make sense for such calculations to optionally consider surface pressures as the 3rd principal stress (-P at applied face, -0.5P at midplane, 0 at outer face) ?

Interesting idea about using pressure as out-of-plane stress. Though it might improve the result, I'd be worried about implications and if it could increase error in some cases.
