Can we do free shape optimization for hyperelastic material (MATHE)? If yes, can i get any reference model for this.

Hello Team,

 

 I want do free shape optimisation of hyperelastic material profile. Is it possible in optistruct . If yes, can i get some reference file for this.

Thank oyu.

    Hi Prasad,

    It's possible to run a free shape optimization using Hyperelastic material.
    However, you need to remind that correctly solving problems involving hyperelastic parts generally requires that a large displacement solution be enabled but small displacement is also supported (large displacement is not supported in shape optimization).
    Also, I'm using a completely generic MATHE in the model attached using dummy settings only to show you a simple model converging. So, it could be better to create your own model with the correct material and settings.
    Please let me know if it works for you, and consider marking the answer as correct if it responds to your question.

    Thank you very much

    Hello Robinson,

     

     Thank you for update. I will try to build model on same line and try to  carry out the analysis.

    Thank you for your help.
