Hi out there,

Tian Tang contributed quite interesting developments from simple stressFoam towards more complicated solvers for the analyis of poroelastic media:

https://bitbucket.org/tiantang/minigeotechfoam.git

I wonder weather slope deformation and failure mechanism analysis could be dealt with the large strain approach developed by Tian ( Large-deformation-elasto-plasticity-solver).

Following the details in :

T. Tang, O. Hededal, P. Cardiff, On finite volume method implementation of poro-elasto-plasticity soil model, INTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS, DOI: 10.1002/nag.2361.

the creation of what should be named Large-deformation-elasto-plasticity-biot-solver would "only" require the implementation of the conservation equation of water flow and a nice segregated coupling of fluid pressure and displacement. I mean, that sounds quite straight forward. However I am not such an experienced "foamer" (in fact just got involved just after reading Tians papers) and such a development might bring me to some "edge"...

Before starting this challenge I would like to know if anybody has some experience with the large deformation approach considering poroelasticity. I imagine the geometrical (large deformation) and material non-linearity (due to plasticity) are already immense. What if additional non-linearity is induced by the strong fluid-solid coupling?

Any hints on large deformation solvers considering poroelasticity are warmly appreciated!

Tom
