Bauschinger ANSYS combin Element

[hercend08]

Hello everyone,

I was wondering if anybody in here ever captured the Bauschinger effects with spring elements in ANSYS APDL.

I have applied a cyclic loading on a uniaxial spring (with steel properties) and trying to mimic possible strain hardening/softening

I have tried Combin39 alone or with Chaboche material properties but did not manage to make it work

Please help

Thanks

If your spring element is elastic only it will not be possible
to observe a Bauschinger effect. For that you need plasticity.
If you model with a spring element in parallel with a frictional slider
you will get something like Bauschinger's stress-strain loops.
