Orientations of principal vectors - CAE
Orientations of principal vectors - CAE
(OP)
Hi,
What is the best way to retrieve the orientations of the principal strains and stresses in the global coord. system.
I would like to do this in CAE.
I want to know for eg., what are the angles the principal strain make with the XY plane and the Y axis.
Let me also mention here that there are some elements in the model with zero strains and displacements.
Thanks
SS

By default, this will plot the Principal stress directions.
You will likely need to scale the size of the arrows. From the menu:
Options... Symbol...
On the "Color & Style" tab, select "screen size" and move the slider until the arrows are a size that you like.
If you want the actual directions in numerical format, you have at least these two choices:
1) Follow the example "Calculation of principal stresses and strains and their directions: FPRIN" in the abaqus doc, or
2) If you store the full stress matrix S (e.g. components are s11, s12, etc.) then you should be able to use that to calculate the principal directions of stress.
