Simple 3D elasticity deal.ii example code saving principal stresses ?

[C B]

Hello deal.ii community, please, could you share any simple 3D elasticity example code saving principal stresses ?  E.g. hexahedral mesh, 2nd order elements. Simple BCs to produce a constant or linearly varying stress field.

Thanks!

C B:
can you say what exactly you mean by "saving" the stresses? Do you want to
visualize it? And by "principal stresses", I assume you mean the eigenvalues
of the stress tensor?
