Nonlinear material behaviour in topology optimization

Hi everyone,

I’m currently doing some work regarding topology optimization in the civil engineering industry. One of the focuses of this work is to try to combine topology optimization with nonlinear material behaviour. I already worked with Abaqus regarding nonlinear static analysis using the concrete damaged plasticity constitutive model and with topology optimization assuming linear material behaviour.

I was searching for this topic online and I found the Altair software, which seems to be advanced regarding topology optimization.

I’m wondering if is possible to perform topology optimization processes considering the nonlinear behavior of concrete material, using altair products such as optistruct. 

If not, even if you know or have some idea/suggestion about how this could be performed, (for example combining this software with some external programming), would serve as a great help in my work.

Thanks in advance,

Best regards,
