13. H modeling

13.1. Characteristics of modeling

Simulation at the hardware point. The objective is to validate the compatibility of CALC_ESSAI_GEOMECA with the MCC behavior model. To do this, a monotonous drained triaxial test with imposed displacement ESSAI_TRIA_DR_M_D is carried out. The number of time steps is \(200\); the lockdown pressure is \(1\) MPa; the maximum axial deformation is equal to 5% under compression. The convergence criterion is \(10^{-10}\).

The parameters for model MCC are given in Section 13.2.

13.2. Tested sizes and results

Two non-regression tests are carried out at the end of the test on components SIG_LAT (lateral stress, SIXX or SIYY) and SIG_AXI (axial stress, SIZZ) components. Note that these constraints are positive (convention followed here by soil mechanics). The responses correspond to an evolution with positive work-hardening and contractiveness.
