Hello,
To get the Cauchy stress, we have to evaluate the term *ev_cauchy_stress*, however, it does not seem to be compatible with a shell10X term-based problem. Is there a way to get Cauchy stress and strain when dealing with a shell model?
Best regards.

Hello Guillaume,
the shell10x term does not allow getting the stress in its current form - it was implemented as a proof-of-concept thing and not much used since (AFAIK), so there are still some omissions. It would be possible to add a stress computation mode to the term, analogously to, for example, the hyperelastic terms, but we do not have resources to do that now. (Of course, contributions are welcome!)
Best regards, r.

Think of dividing some continuous material into super small cubes. If you pick three perpendicular surfaces of these cubes you can define 3 stress tensor components for each, that represent the pull/push/sideways stress per distance unit that this cube element feels under any conditions. The combined stress of each of these cubes describe the stress that the material feels at every point.
They are useful because in isotropic mediums under simple stress you can find relatively simple expressions for the stress tensor in every point. <a href=" https://essayschief.com ">Click here...</a>
