7. E modeling

It should be noted that modeling E concerns the use of model CSSM [r7.01.44]. It is characterized by:

• A hydrostatic compression path in drained condition up to a pressure equal to \(100\) kPa.

• An undrained path by maintaining lateral stresses on the sample while imposing a vertical compression displacement.

7.1. Characteristics of modeling

Same as modeling A.

7.2. Tested sizes and results

At moment \(t=2\), at the end of an undrained load path, the components \(\sigma'_{xx}\) and \(\sigma'_{zz}\) of the effective stress tensor, and water pressure \(PRE1\), are tested at node NO8. The reference values are non-regression values.
