v6.07.101 COMP001 — Elasto-plastic behavior test. Simulation at a hardware point

Summary:

This test involves a simulation of a loading path in stresses or deformations at a material point, i.e. on a model such that the stress and deformation states are homogeneous at all times. It thus makes it possible to test a certain number of elastoplastic behavior models, in order to verify the robustness of their numerical integration, their insensitivity to a change of units, the correct consideration of the control variables on which the coefficients of the model depend, the invariance with respect to a global rotation applied to the problem, the accuracy of the tangent matrix.

Modeling A: this modeling makes it possible to validate model VMIS_ISOT_LINE in 3D and C_ PLAN.

B modeling: this modeling makes it possible to validate model VMIS_ISOT_TRAC in 3D and C_ PLAN.

C modeling: this modeling makes it possible to validate model VMIS_CINE_LINE in 3D.

D modeling: this modeling makes it possible to validate model VMIS_ECMI_LINE in 3D and C_ PLAN.

E modeling: this modeling makes it possible to validate model VMIS_ECMI_TRAC in 3D and C_ PLAN.

F modeling: this modeling makes it possible to validate model VMIS_CIN1_CHAB in 3D.

G modeling: this modeling makes it possible to validate model VMIS_CIN2_CHAB in 3D.

H modeling: this modeling makes it possible to validate model VMIS_ISOT_PUIS in 3D.

J modeling: this modeling makes it possible to validate model MOHR_COULOMB in 3D.

K modeling: this modeling makes it possible to validate the MohrCoulombas model in 3D.

L modeling: this modeling makes it possible to validate model NLH_CSRM in 3D.
