v7.31.122 WTNV122 - Undrained triaxial test with behavior models CAM_CLAY, MCC and CSSM

Summary:

This test makes it possible to validate specific elasto-plastic mechanical laws CAM_CLAY, MCC and CSSM to the behavior of soils. Five different models are carried out in 3D, the first three using the model CAM_CLAY [r7.01.14], the fourth with the model MCC [r7.01.48] and the fifth with the model CSSM [r7.01.44]. In each model, the test is carried out using hydro-mechanical coupling and includes two loading paths:

• A hydrostatic compression path in drained condition.

• An undrained vertical compression path while maintaining constant lateral stresses.
