v6.08.111 SSND111 - Memory effect in a cyclic test

Summary:

On a problem that is reduced to the material point, several traction-compression cycles are carried out, until the response is stabilized in terms of the imposed stress-strain curve. Taking into account the memory effect of greater work hardening changes the stabilized curve. This test highlights this memory effect for Code_Aster behaviors that allow it to be modelled.

Modeling A: this modeling makes it possible to validate behaviors VISCOCHAB and VISC_CIN2_MEMO with SIMU_POINT_MAT.
