Topological Optimization - Preserve stress distribution at interface

Recommended Posts

Hello,

I have two objects in contact. I would like to know if it's possible to perform a topological optimization of a part, ex changing the material, so that the stress distribution at the interface between the two parts remains the same as before. Thank you for the attention.

As i think, first you need to do contact analysis, after that you extract contact forces

Then use those forces as BC for topology optimization of single part. You need to constraint it.

All Optimization disciplines using nonlinear solution with contact only has been supported in OS for a long time.In V2018, nonlinear responses have been added.Contact pressure and contact force from both S2S and N2S contacts can now be used as a response (DRESP1) in optimization formulation. Refer attached model for contact pressure response for shape optimization. Use latest version and refer online help for detailed information.
