3. Modeling A#
3.1. 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 (\(\mathrm{\beta }=\mathrm{0,25}\) and \(\mathrm{\gamma }=\mathrm{0,5}\)) 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.
3.2. Tested sizes and results#
The value of the irreversible displacement is tested at various times estimated by the Newmark method.
