What is IN-PLANE PRINCIPAL STRESS in Abaqus?
(OP)
Hi everybody!
I'm doing a Static analysis of a circular reinforced concrete slab.
I'm using SHELL elements in ABAQUS.
In the OUTPUT there are these variables:
MAX IN-PLANE PRINCIPAL STRESS
MIN IN-PLANE PRINCIPAL STRESS
MAX PRINCIPAL STRESS
MIN PRINCIPAL STRESS
What is the difference? And what is the principal stress that I need?
Thank you
Regards

Max in plane principal stress grabs the highest value of (2).
Max principal stress grabs the highest value of (1) and (2).

But I'm not sure because I'm considering a SHELL element that has a PLANE STRESS hypotheses.
In fact there are only these stresses: S11 S22 (that are normal) and S12 that is a shear stress.
When I find a plane without shear I'll find only 2 stresses (that are normal). I think this is all. Is it correct?

So I should have only 2 principal stresses, shouldn't I?

IN-PLANE PRINCIPAL STRESSES or PRINCIPAL STRESSES ?

In fact I can't understand which I have to consider.
