4. Features and verification

The law of HUJEUX (HUJEUX behavior for the COMPORTEMENT keyword) can be used in*Code_Aster* with different models:

• classic version: 3D, D_ PLAN,

• sub-integrated finite elements: 3D_SI, D_ PLAN_SI,

• combined with the models from THM (cf. [R7.01.11]): 3D_ HMD, D_ PLAN_HMD…

The HUJEUX model can also be used in*Code_Aster* with various types of integration schemes (ALGO_INTE): “NEWTON”, “NEWTON_RELI”, “NEWTON_PERT”, “SEMI_EXPLICITE”, “”, “BASCULE_EXPLICITE”, “SPECIFIQUE”.

Attention:

The validity of the 3D formulation of the Hujeux law seems questionable (cf. Appendix 3). It is therefore necessary to adopt a certain degree of caution when using it in this context.

Here is the list of available validation cases:
