stress-strain curve without post-peak phase

Asked by Yushu WANG

Hello,
I use TriaxialStressController engine to generate the stress-strain curve according script-session1.py, but I can't get the curve with post-peak phase. The link of my result is https://products.aspose.app/imaging/zh-hans/viewer?foldername=a49b0cbc-106a-4a67-8e5b-461a42ccf526&filename=c0dc31d99f3f4ae6e1638c88b6e4f4d.png.
And the simulation has the error of https://products.aspose.app/imaging/zh-hans/viewer?foldername=6d3245ef-f72d-4904-8917-bc5ead8c5b68&filename=8bd6bde031106bf660ada3b1ff9d803.png. It happens at the end of simulation.
The link of my code is https://nextcloud.univ-lille.fr/index.php/s/A7XfTnGwFPgtMmK.
Is there something wrong with my parameter settings? How should I modify it ?

Looking forward for your help.

Best regard,
Yushu WANG

Hi Yushu,

They already migrated the YADE questions forum to the following website:
https://gitlab.com/yade-dev/answers/-/issues

For your first question, this is related to the relative density of the packing. If the packing is in a loose state. Definitely, you can't get the post-peak stage (I think you are referring to the softening stage ).

For the second question, I don't know the reason. But maybe it's related to your parameters. I did the triaxial simulation before. I can run the code without any problems.
