v7.33.110 WTNA110 — Axisymmetric modeling of clay swelling with the GONFElas model

Summary:

This test makes it possible to validate the so-called « GonfElas » model. This non-linear elastic model, dependent on suction, describes the swelling behavior of certain types of clay. Typically it is used to model the behavior of compacted clay plugs - or bentonite - used to close radioactive waste storage cells. It is a very simplified version (elastic part) of the Barcelona model.

This model is written according to the following pair of variables: net stress and suction (suction is capillary pressure).
