Units Stress strain table

[Michel1978]

Hello,
I'm filling out a stress/strain table for a nonlinear calculation but wonder what the unit for the stress is. In the documentation I saw it was psi, but is it always psi?

I use NX6.

Here is something I found that should answer your question:

Hello!,
In the material properties definition you have the properties you are using, for instance for Young Module. If you created your SIM or FEM file in inches then surely your stress units are PSI, you can see the units in your window. The Strain values are unitless.
Best regards,
Blas.

I know strain is unitless. And I use the metric system thus normally stress is displayed in MPa / N/mm^2. But for nonlinear you need to fill out a stress/strain table for which you can not choose which units you like to use. For all other properties it is possible to choose.


I use NX6.

Hello!,
In NX7.5 (the program I run) the user choose the units to define the stress-strain curve to avoid any error.
Best regards,
Blas.
