Obtaining membrane, bending and peak stresses from grip point stresses
Altair EmployeeDear all,
I'm trying to calculate the membrane, bending and peak stresses after a static calculation with chexa elements.
I'm using GPSTRESS(PUNCH)=1 to obtain the grid point stresses from a header set (ID=1) that contains the grids of my stress classification line.
What I see in the punch-file is the follwing (3-grid-stress-classification line):
$TITLE = (OS 2017.2.4)
$SUBTITLE=
$LABEL = C-PROFIL
$GRID POINT STRESSES (PROPERTY 500)
$REAL OUTPUT
$SUBCASE ID = 1
558868 -2.299386E+02 1.892927E+01 -4.929673E+02
-CONT- -1.190178E-03 -1.285024E+01 -3.648179E-03

-CONT- 2.958188E+01 8.705740E+01
Questions:
- Which entry is which stress (I probably need need S11,S22,S33,S12,S13,S23, but I can't assign them)
-How do I calculate the membrane, bending and peak stresses, when I have correctly assigned the stresses?
Thanks for your help
Kind regards

You did not attach the model here, so I can not tell you the order of the stress tensors in this GSTRESS pch file, but if you want you can find my answer in another topic:
