[SOLVED] Hyperelastic materials related paper

[Noura]

Hello,

I’m looking into the HyperelasticMaterial implemented in SOFA, and already found a nice illustrative scene TetrahedronHyperelasticityFEMForceField_test.scn using the TetrahedronHyperelasticityFEMForceField component.

Could anyone refer me to a SOFA related paper if any?
I haven’t a solid background in mechanics, and I would need more understanding of the related constitutive law (MooneyRivlin material is used here I think), about the strain energy function and the basic parameter set.

Thanks,

Noura

BTW, I noticed that TetrahedronHyperelasticityFEMForceField_params_test is failing on my configurations.

More precisely, I need some clarification of the parameters d_materialName, d_parameterSet, and d_anisotropySet which should be set in the force field.

Hi Noura,

Sorry for the delay, I dug a bit to see if any paper was mentioning the open-source code and theory for hyperelasticity. The papers I found were mainly referring to the a discretization method, the Multiplicative Jacobian Energy Decomposition (MJED) which is an alternative to the classical Galerkin FEM (Finite Element Method) formulation.

You can get inspired from usual theoretical books.
Sorry not to help more. In case you write anything, it would be nice to improve the associated documentation, keep us updated!

Best,

Hugo
