3. Modeling A#

3.1. Characteristics of modeling#

A material point subject to the \(13.5\) cycles of imposed deformation, from which the last one is extracted. Three successive calculations are performed with behaviors VISCOCHAB with integration IMPLICITE, VISCOCHAB with integration RUNGE_KUTTA (used as a reference solution) and VISC_CIN2_CHAB with integration IMPLICITE.
