Jérôme Duriez proposed the following answer:
Hi,
What is sure is that you eventually comparing two stress expressions
that are quite different:
- PIC uses some totalForceInVolume [*] expression I'm totally unfamiliar with
(=> which I can not justify at the moment / ever ?)
- getStress is the classical Love-Weber formula.
Please open an issue about that engine, especially if you think there is
another issue about unbalanced force test (from another discussion)
