Stress at particular strain
Stress at particular strain
(OP)
Hello users,
How to get stress values at particular strain or displacement like 5%, 10%, 15% and so on.
In my compression analysis, i get results randomly.
I use abaqus CAE.
Thanks for your time and help.

RE: Stress at particular strain
I have no idea how you can get apparently random results from a model.

I am not sure that I can exactly understand your question. But users can obtained the evolution of the stress/strain at particular integration point of an element from either history or field data.
Ehm... what do you mean by random results ?

random results means - i get stress results at 3%,7%,11% ... strain.
But i need, exactly at 5%, 10%,.. and so on.
I tried minimizing time increment. But, no success.
I have non-linear geometry on and material curve also highly non-linear.
I read somewhere, it is possible only for linear analysis.
For non-linear, it must be extrapolated from existing values.
is it true?
Thanks for time and help. Excuse me for late reply.

If you mean that you wish to display the strain plots at 5%, 10% etc, you can go to the contour options and change the limit from auto compute to 5% (or whichever strain value you like).
You can try what Yoman suggested, but with non-linear material it is really unpredictable and you will lengthen solution time. You can make displacement/load/temp increase ramp as you like by editing increment specs, but strain is a behavior dictated by inherent material property.
That's all I can offer. Hope this helps.
