    Status: Open => Answered

Jan Stránský proposed the following answer:
It depends on how you apply the loading and what you want to achieve.

For example, one approach would be first to fully apply the transverse stress and then start the axial loading.
In that case, you can just simply call
###
for b in O.bodies:
    b.state.refPos = b.state.pos
###
when the model is relaxed after transverse loading, just before the axial loading.
Then you use the same code for strain evaluation.

Currently you start applying transverse stress and the axial loading at
the same time. Transverse stress takes some time to be applied and thus
may somehow influence or even corrupt the results. Depends on how much
time it needs to be applied.


Concerning the second part, yes, I think simple "vertical shift" is fine.

Cheers
Jan
