Any additional mechanical constitutive laws?

[hugtalbot]

We are thinking about implementing additional mechanical constitutive laws in SOFA (maybe through the Caribou plugin). Is there any need of mechanical constitutive laws missing in SOFA?

💡 💡 💡

• Yeoh, maybe?
• higher order polynomial hyperelastic model?

Please let us know 👇 👇 👇

Hello,
On our hand Mathias mentionned Yeoh indeed, but we are not working on such mechanical constitutive laws impacts in our simulations right now, so this is theoretical need ...
I would had that when we talked about it (several months ago) Mathias suggested he could help with/assess the implementations if needed.

Thanks anyway.

Thanks @remibessard 🙌

@hugtalbot I think it is worth looking at the work done in Caribou last year to integrate FEniCS into SOFA. If I remember correctly, in the current state of the branch, the c++ code generated from FEniCS for different mechanical equations can be integrated into Caribou, but requires a manual compilation of the code. I think it would not be that much work to do this automatically by, for example, generating and compiling the code of the python equation at the first load of the simulation.

This would be a very powerful tool to integrate many new constitutive laws into SOFA.

It's actually a question related to it @jnbrunet ;)
We aim at using SOniCS to implement a serie of constitutive laws easily at once 👍
