Modeling A
==============


Characteristics of modeling
-----------------------------------

Modeling A uses a behavior model for the linear dam, the calculation being performed using the DYNA_VIBRA operator on a physical and temporal basis, with an undamped Newmark temporal integration scheme (:math:`\mathrm{\beta }=\mathrm{0,25}` and :math:`\mathrm{\gamma }=\mathrm{0,5}`) and a modal damping reduced by 0.01%.

For modeling A, we use the definition of the circle from the keywords RAYON, CENTRE_X and CENTRE_Y as well as from a sufficiently refined 2D auxiliary mesh of the same circle using the keyword MAILLAGE_GLIS.


Tested sizes and results
------------------------------

The value of the irreversible displacement is tested at various times estimated by the Newmark method.
