4. B modeling#
4.1. 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 (\(\mathrm{\beta }=\mathrm{0,25}\) and \(\mathrm{\gamma }=\mathrm{0,5}\)) can be used.
4.2. Tested sizes and results#
The value of the irreversible displacement is tested at various times estimated by the Newmark method.
