Implement the modified cam-clay model for unsaturated soil behavior

[Auubinno]

Hello, I need to implement the modified Cam-Clay model for unsaturated soils in Code_Aster, and I am considering using MFront as it seems much simpler than modifying the source code.

In the implementation, I intend to include a term that considers the increment of saturation due solely to the increment of stress. Therefore, the saturation must be updated during the numerical integration step along with the stresses. Is it possible, through MFront, to modify the internal variable related to the change in saturation present in the HM model?

@Auubinno You shall receive information from the aster team soon.

@Auubinno,

I think you can find some information by following these two links:

• Barcelone
• MCC

These constitutive models have recently been implemented in the unstable version of code_aster.

Thanks @thelfer and @SRaude.

I'll take a look at those files.
