v6.02.106 SSNL106 - Elastoplastic beam in pure tension and bending

Summary:

This test validates the elastoplasticity in a straight beam under tension and flexure, for perfect elastoplastic behavior or linear work hardening as well as options for the post-treatment of the beams.

• Static analysis,

• Elastic behavior,

• Elastoplastic behavior,

• 3 sections: rectangular, solid circular, hollow circular,

• 1 types of work hardening: linear (VMIS_ISOT_LINE and VMIS_ISOT_NL reduced to the linear case)

The models make it possible to test elements POU_D_E (SEULEMENT EN É LASTICITÉ), POU_D_TGM, POU_D_EM, TUYAU_3M (3 and 4 knots) COQUE_3D.

The test makes it possible to validate the functioning of the integration of these laws of behavior and of the resolution algorithm until the complete plasticization of the beam.

one of the models makes it possible to test the operation of DYNA_NON_LINE on a quasi‑static calculation of the traction of a beam modelled in POU_D_TGM.

In addition, G modeling is used to test how the STAT_NON_LINE keyword factor ETAT_INIT works with the structure field STRX_ELGA.
