Maximum stress limit

Altair Forum User

I am making topology optimization for a rotating disk. Yield strength for my disk is 828 MPa, which means in my optimized design I shouldn't pass that limit. However in element density I did't see any limitation. I specified in design constraints that my von mises stress won't pass 828 MPa and I can see that in results I didn't pass yield strength. But I don't know which parameters refer to those stresses. Can anyone help me about that.

Thanks in advance

Hi Mehmet,

 

Toplogy optimization filters the stress results. So there wont be any stress concentration. With this said you can't base your results in the stress obtained in this optimization.

You must do a static study of the optimized smooth geometry in order to get the correct stresses.
