B modeling
==============


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

Modeling A uses the Iwan behavior model for the dam. The calculation is carried out using the operator DYNA_NON_LINE. However, the load is small enough that the results of the elastic calculation of modeling A can be used as a reference solution for modeling B. An undamped Newmark temporal integration scheme (:math:`\mathrm{\beta }=\mathrm{0,25}` and :math:`\mathrm{\gamma }=\mathrm{0,5}`) can be used.


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

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