plastic curve plst

[lcasprini]

I know. The factor "1" is a mistake that I already removed.
But as you said, is not the problem.
In general, the "plastic curve" seems not to work.

Although I continue to try.

Thank you for your help

Hi lcasprini. I m not convinced that the problem lies with the 'plst' link. I changed it to a 'bl_kin' link and still get the yielding with very small deformations. I'll continue to look the model over, but have yet to discover exactly what is going on.
