How to distinguish failure point in a loaded beam ?

Please login with a confirmed email address before reporting spam

Hi, friends

I built a simple concrete beam with 2 loads. (I didn't use "beam" node, as I want to add Heat & Moisture transfer later)
I want to investigate faiure point (Nonlinear Elastic Material> Concrete > Ottosen), but it leads to error in 400 N load: (No problem in 300N load)

Iteration for finding elasto-plastic strain variables did not converge

It is interesting that when I disable "concrete", the error vanishes. Did my small concrete beam (607.510 cm) fails in 400 N ?

Regards, W.S.
