Elasticity measurement

[Bence]

Hi,

I would like to know, is it possible to simulate and measure elasticity with Sofa?
Our problem is: We want to investigate the trachea. We segmented the trachea from CT then import to the Sofa, and would like to see when will be break away if we pulled on both sidest.
Is it possible to simulated? If not can anyone offer a program for this task?

Best Regards!

Hi @bence

Interesting topic!
We have models to handle thin 3D objects like a trachea. You can for instance see the QuadBendingFEMForceField introduced by Nhang in #1745.

However, this is a mechanical constitutive law (you can find functions computing the material strain or the material stiffness). However, if you want your material to break, this need to be additionally defined (tearing threshold).

I know that InfinyTech3D is working on such topics.

Best,

Hugo
