[Issue] FEM stress linearization calculation #8268

[giorgiugo]

I paste the issue in this forum.

I read the code of the stress linearization tool (PostFilterLinearizedStresses).
The formulas use xdata (discretizazion of the line) and ydata (equivalent stress, e.g. Von Mises) of the previous tool (PostFilterDataAlongLine) .
But the membrane and bending stresses must only be calculated from the six components of the stress tensor, taking in account the components of these stresses rispectively tangential and normal to the line (SCL).
After that the stresses can be ricombinated in a Von Mises stress.
Can anyone check the code?
Thanks

Thank you.
The exact calculation procedure is contained in ASME VIII div.2 5-A.4.1.2
